LA5645T
Constant-Voltage/Constant-Current Control IC
Overview
The LA5645T is a constant-voltage/constant-current
control IC that incorporates low-voltage operational
amplifiers and a high-precision reference voltage circuit
(VREF = 1.5 V ±1.0%). This device is optimal for use as a
secondary side controller in battery chargers, switching
regulators, and similar products.
