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)
