SY8511adc

General Description

SY8511 is a high efficiency, current mode adaptive

constant off time controlled asynchronous step-down

DC/DC converter capable of delivering 0.6A output

current. The SY8511 operates over a wide input

voltage range from 4.5V to 100V and integrates main

switch with very low RDS(ON) to minimize the

conduction loss.
