Overview

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.)
