TPS65561 Photo Flash Capacitor Charger

TPS65561 描述

This device offers a complete solution for charging a photo flash capacitor from battery input, and subsequently discharging the capacitor to the xenon tube. The device has an integrated power switch, IGBT driver, and control logic blocks for charge applications. Compared with discrete solutions, the device significantly reduces the component count, shrinks the solution size, and eases design complexity. Additional advantages are fast charging time and high efficiency due to the optimized PWM control algorithm. Other provisions of the device includes four options for determining a different target voltage, programmable peak current, thermal disable monitor, input signal for charge enable, flash enable, and an output signal for charge completion status
