TPA7253A

概述

The device combines a dual operational amplifier and a fixed 2.5-V shunt voltage reference, which are often used in the control circuitry of power supplies.

The operational amplifier A has the non-inverting input internally tied to the shunt reference which is used for the voltage control loop. The operational amplifier B is independent of the current control loop.

The device has a 220-μA power supply excluding the current in the reference, and the minimum working current for the reference is 50 μA, which can be used in low-power applications.
