Monolithic Linear IC
LA5683T
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.
