S-8533 Series

STEP-DOWN, SYNCHRONOUS PWM CONTROL

SWITCHING REGULATOR CONTROLLER

Rev.3.0

_02

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 compensation circuit, and PWM controller.

An efficient step-down switching regulator can be realized simply by adding external P-channel and N-channel power MOS

FETs, one coil, and three capacitors.

Since the oscillation frequency is a high 300 kHz, the S-8533 can be used to configure a high efficiency step-down switching

regulator capable of driving high output current using small external parts and a 3 to 10% increase in efficiency is obtained

compared to conventional step-down switching regulators.

The 8-Pin TSSOP package and high oscillation frequency make the S-8533 ideal as the main power supply for portable

devices.
