The STLC1, a device realized with the well established BCD technology, is a fixed frequency fully monolithic SMPS, with three independent smart low side driver, primarily intended for automotive rear led lamps driving.
The STLC1 output voltage is set using a simple resistor divider. Thermal shutdown with hysteresis, input over-voltage and overcurrent protections give robust design solutions.
