LA5683T Datasheet | SANYO

Overview 4ch Switching Regulator Control IC The LA5683T is 4ch switching regulator control IC. Functions - Low-voltage operation (minimum 1.8V). - OUT1 and OUT2 can drive external PNP transistors. - OUT3 and OUT4 can drive external NPN transistors. - 4-independent-channel standby circuit built-in. - ±1% accuracy reference voltage. - Supports MOS transistor drive. - Channel 2 dead time internally set fixed, duty cycle = 100%. (The dead time for channels 1, 3, and 4 are set externally.)
