恒流操作
LIS8712 采用专利的恒流驱动技术，通过采用这种
技术，可以使输出电压在极宽的的范围内恒流。而
且可以确保输出电流和变压器感量无关，从而加大
了系统设计的容差。系统的输出电流可以表示为：
I
0.25
∗
N N
∗I
Adj 对 GND 开路
电流分档 LIS8712 集成了电流分档功能，参考恒流计算公式， 在大批量生产应用时，由于输出电流的多样性需求， 往往需要一个变压器规格能够适应多种输出电流规 格，且能保证良好的开路及短路保护功能，该特性 满足了这类应用。不仅如此，该功能还可使变压器 的工作频率无需大幅度变化，方便变压器的设计及 保障系统的可靠性及安全工作区域。更重要的是即 时系统板在轻微受潮的情况下，依然能正常工作， 配合 SOP-7 的封装形式，大大提升了系统的稳定性。
图1 由于不受辅助线圈供电限制，并且具有宽范围的工 作频率，即使系统输出在 4 颗灯至 7 颗灯的额定电 压情况下，仍能保证良好的恒流特性，为设计系列 机种提供良好基础。
电流可调整范围（无需变换变压器）
图3 图2
由于 IC 具有电流分档功能，当 Adj 脚对地开路时， 系统以最大电流输出，当 Adj 脚对地短路时，系统 以额定电流的 85%进行输出，再配合 CS 脚电阻的 调整，在输出保护电压不大幅度波动的情况下，可 以实现 0.67 倍至 1 倍电流的输出变化。相比于传 统的可设定 OVP 电压，仅靠调整 CS 电阻来改变输 出电流的方案，大大拓展了输出电流的范围，同时 变压器的工作频率也能得到充分利用，同一变压器 频率变化较小。
