PW2558芯片代理，原装现货，技术支援

GENERAL DESCRIPTION

The PW2558 develops a high efficiency asynchronous step down DC/DC regulator capable of

delivering 0.8A output current. The IC adopts current mode adaptive constant off time control. The

PW2558 operates over a wide input voltage range from 4.5V to 55V and integrates main switch with

very low RDS(ON) to minimize the conduction loss. Low output voltage ripple and small external

inductor and capacitor sizes are achieved with 1.2MHz switching frequency.
