具有 VIN 接地
短路保护的典型应用,使用 A8502 LED 驱动器的可选 P-MOSFET 感应。 A8502 是一款用于小尺寸 LCD 背光的多输出白光 LED 驱动器。它集成了一个电流模式升压转换器、内部电源开关和两个电流吸收器。该升压转换器最多可驱动 24 个 LED,每串 12 个 LED,电流为 120 mA。 LED 接收器可以
并联在一起以获得更高的 LED 电流,高达 240 mA。 A8502 可以使用 5 至 40 V 的单电源运行

Typical Application with VIN to ground short protection, using optional P-MOSFET sensing for A8502 LED Driver. The A8502 is a multi-output white LED driver for small-size LCD backlighting. It integrates a current-mode boost converter with internal power switch and two current sinks. The boost converter can drive up to 24 LEDs, 12 LEDs per string, at 120 mA. The LED sinks can be paralleled together to achieve even higher LED currents, up to 240 mA. The A8502 can operate with a single power supply, from 5 to 40 V
