各种LED恒流驱动及恒流IC芯片盘点LED恒流驱动简介山于LED是特性敬感的半导体器件，乂具有负温度特性，因而在应用过程中需要对其进行稳定工作状态和保护，从而产生了驱动的概念。

LED器件对驱动电源的要求近乎于苛刻, LED不像普通的白炽灯泡，可以直接连接220V的交流市电。

LED是2〜3伏的低电压驱动, 必须要设计复杂的变换电路，不同用途的LED灯，要配备不同的电源适配器。

国际市场上国外客户对LED驱动电源的效率转换、有效功率、恒流精度、电源寿命、电磁兼容的要求都非常高，设计一款好的电源必须要综合考虑这些因数，因为电源在整个灯具中的作用就好比像人的心脏一样重要。

LED驱动电源把电源供应转换为特定的电压电流以驱动LED发光的电压转换器，通常情况下：LED驱动电源的输入包括高压工频交流（即市电）、低压直流、高压直流、低压高频交流（如电子变压器的输出）等。

而LED驱动电源的输出则大多数为可随LED正向压降值变化而改变电压的恒定电流源。

LED电源核心元件包括开关控制器、电感器、开关元器件（MOSFET）.反馈电阻、输入滤波器件、输出滤波器件等等。

根据不同场合要求、还要有输入过压保护电路、输入欠压保护电路，LED开路保护、过流保护等电路。

LED的恒流驱动用LED作为显示器或其他照明设备或背光源时，需要对其进行恒流驱动，主要原因是:1.避免驱动电流超出最大额定值，影响其可鼎性。

2.获得预期的亮度要求，并保证各个LED亮度、色度的一致性3.能有效的避免雷击，电网的浪涌，过电流，过电压的保护，使LED寿命提高。

存在问题：要处理好散热问题，散热问题没有处理好就会影响LED寿命。

口前LED均采用直流驱动，因此在市电与LED之间需要加一个电源适配器即LED驱动电源。

它的功能是把交流市电转换成合适LED的直流电。

根据电网的用电规则和LED的驱动特性要求，在选择和设计LED驱动电源时要考虑到以下儿点：1•高可鼎性特别像LED路灯的驱动电源，装在高空，维修不方便，维修的花费也大。

The part integrates current sources and automatic mode selection charge pump. It maintains the high efficiency by utilizing an x1/x2 fractional charge pump and current sources. The small equivalent x1 mode open loop resistance and ultra-low dropout voltage of current source extend the operating time of x1 mode and optimize the efficiency in white LED applications. The operating voltage range is from 2.8V to 5.5V. Internal soft start circuitry effectively reduces the in-rush current while both start-up and mode transition. The load is disconnected from V IN while shutdown and the shutdown current is less than 1uA.High Efficiency x1/x2 Charge PumpBefore the discussion of efficiency in RT9363A, two things need to be illustrated. One is the Li-ion battery life time,the other is the forward voltage of white LED. The Li-ion battery energy is not linearly proportion to battery voltage.In the Figure 6, It shows the 80% battery life of Li-ion is arranged from 3.65V to 4.0V. The other voltage range occupies less than 20% battery energy and is insignificant.In the backlight application, the forward voltage of white LEDs most likely falls in 3.2 to 3.5V @I LED = 20mA. The developing concept of RT9363 is based on the backlight application with Li-ion battery. RT9363A is very cost-effective product for white LEDs backlight driving. It extends the 80% battery life by the reduction of open loop resistance at x1 mode and current source drop out voltage. Figure 7is the efficiency diagram of RT9363 and 80% battery life is marked by red rectangle. The RT9363A maximize the x1 mode operating range in the 80% battery life. Therefore,the efficiency is not significant different to that without x1.5 mode charge pump. The peak efficiency of RT9363A is 93% and the average is 84%. Comparing to the LED drivers with x1.5 mode, only 1 to 2% efficiency loss by x2mode. (Assume 5% battery life in charge pump mode and the efficiency difference of x1.5 and x2 modes is 25%, the efficiency loss thus is 5%x25% = 1.25%).ProtectionThe RT9363A includes a soft start circuit to limit the inrush current at power on and mode transition.Soft start circuit holds the input current level long enough for output capacitor C OUT reaching a desired voltage level.When the soft start off, the RT9363A won't sink spike current from V IN . An over voltage protection function protect the output voltage from dangerous high voltage. The OVP turns off charge pump when the voltage difference between V IN and V OUT is over the designed target.LED Current SettingIn Backlighting part, an internal R SET is used to set the initial current (20mA) of white LED and implements a 4-bit DAC for brightness control. Users can easily configure the LED current by a serial pulse. The dimming of white LEDs'current can be achieved by applying a pulse signal to the EN pin. There are totally 16 steps of current could be set by users. An automatic R SET selection is implemented in this part. RT9363A can automatically select the internal or external R SETs by the connection of ISET pin. The LED current can be calculated by the following equation.where V SET = 1.1V (typ.) and R SET is the external resistor connected from ISET pin to GND.SET LED SET V I = 276R ⎛⎞⎜⎟⎝⎠LED Current Setting TablePCB Board Layoutpad should be connected to a strong ground plane for heat sinking and noise prevention.flying capacitor should be short and wide to reduce parasitic resistance and prevent noise radiation.Output capacitor must be placed close to be placed close to the VIN and connectto GND plane.All the traces of LED and VIN running from chip to LEDs should be wide and short to reduce the parasitic connection resistance and shielded, isolated by ground plane.

Li-ion Battery Energy Capacity Versus BatteryVoltage.Capacity (mAH)Battery Voltage(V)4.24.03.655065080%Battery LifeTypical OperationAs shown in the typical application circuit, the power of the RT9363A is provided from the external adapter or battery. When EN pin is low, the white LED for backlighting is turned off and draws a very low current from battery supply.When EN pin is high, RT9363A provides a twice mode load switch (x1) and high efficiency (x2) charge pump device intended for white LED backlight applications. T o maximize the power conversion efficiency, an internal sensing circuit monitors the voltage required on each constant sink input and sets the load switch and charge pump modes based on the input battery voltage and the current sink input voltage. RT9363A provides the option to control the 16-steps brightness of white LEDs with a digital pulse signal applied to EN pin and the detailed timing of pulse dimming is shown in Figure 5.Capacitors SelectionTo get the better performance of RT9363A, the selection of peripherally appropriate capacitor and value is very important. These capacitors determine some parameters such as input and output ripple, power efficiency, maximum supply current by charge pump, and start-up time.To reduce the input and output ripple effectively, the low ESR ceramic capacitors are recommended. Generally,to reduce the output ripple, increasing the output capacitance C OUT is necessary. However, this will increase the start-up time of output voltage. For LED driver applications, the input voltage ripple is more important than the output ripple. Input ripple is controlled by input capacitor C IN , increasing the value of input capacitance can further reduce the ripple. Practically, the input voltage ripple depends on the power supply's impedance. T antalum capacitors are not recommended for the RT9363A. If tantalum must capacitors are needed, C IN and C FLY must larger than 10μF and 1μF. Because tantalum capacitors'values are less than normal when using for high frequency applications. So tantalum capacitor values and ceramic capacitor values can't be the same. But C OUT can't use tantalum capacitor, because during the x2 mode charge pump the V OUT is negative voltage.11DS9363A-03 April 2011Information that is provided by Richtek Technology Corporation is believed to be accurate and reliable.
