[Outline]
This is a diode rectifier-type step-down DCDC converter IC with integrated Power MOS FET.
The IC operates at a maximum output current of 3A.
This is suitable for power supplies of LCTVs and DVD recorders because of its more stable load transient response
(changes from 1A to 2A, approx. 50mV) and wider input voltage range (7 to 27V) .
