General Description The HM3512 is a 150 KHz fixed frequency PWM buck (step-down) DC/DC converter, capable of driving a 2.4A load with high efficiency, low ripple and excellent line and load regulation. Requiring a minimum number of external components, the regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator. The HM3512 built in output short protection function. When short protection function happens, the chip will be ...
