Rev.1.1 Synchronous PWM control Step-Down Switching Regulator-Controllers S-8532 Series The S-8532 series is a family of CMOS synchronous PWM control stepdown switching regulator-controllers consisting of a reference voltage source, oscillation circuit, an error amplifier, phase compensation circuit, PWM control circuit. A high efficiency and large current step-down switching regulator is realized by only adding a P-channel and an N-channel power MOSFETs, a coil, and 3 capacitors. Small external components can be used due to the high frequency oscillation at 300kHz. The efficiency of the switching regulator should be 3 to 10% higher than that of the conventional step-down switching regulator.
