S-8533 Description
STEP-DOWN, SYNCHRONOUS PWM CONTROL SWITCHING REGULATOR CONTROLLER S-8533 Series The S-8533 Series is a synchronous PWM control CMOS step-down switching regulator controller that includes a reference voltage source, synchronous circuit, oscillation circuit, error amplifier, phase pensation circuit, and PWM controller. An efficient step-down switching regulator can be realized simply by adding external P-channel and...
