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.)
