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.
Features
Operating supply voltage: 2.5 to 14 V
High-precision reference voltage: 1.5 V ±1.0%
PC pin current: 60 mA (max)
Current drain: 3 mA (max)
Input offset voltage: 2 mV (max)
