General Description

The ADP2450 integrates one boost shunt controller with power detection, one high efficiency buck regulator, four low offset, low power consumption programmable gain amplifiers (PGAs), one low offset operation amplifier, a fast analog trip circuit, and an actuator driver.

The ADP2450 is targeted for low voltage circuit breakers, such as the molded case circuit breaker (MCCB), and current transformer (CT) powered supply applications.

The boost output voltage can be up to 36 V and integrates a power detection circuit that prevents the circuit from power hiccups.
