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.
