The ACT4523YH-T from Qorvo is a synchronous step-down (buck) DC-DC converter offering a wide input voltage range of 10V to 38V. It provides an adjustable output from 0.808V to 12V with up to 3A of output current. The fixed 225kHz switching frequency balances efficiency and component size. Packaged in an 8-SOIC with exposed pad, it is designed for automotive, industrial, and telecom power applications requiring robust performance.
- Extended Input Range: Handles up to 38V input, making it suitable for automotive load-dump and industrial 24V systems.
- Reliable 3A Output: Provides sufficient current for multiple digital loads or single high-power ICs.
- Proven Package: The 8-SOIC exposed pad package offers good thermal performance and is widely available.
- Simple Fixed Frequency: 225kHz switching frequency simplifies EMI filter design and ensures predictable operation.
Automotive Infotainment
The ACT4523YH-T's 10V to 38V input range is well-suited for automotive infotainment systems that must operate during cold-crank (down to 10V) and load-dump (up to 38V) conditions. It provides a stable 3.3V or 5V rail for audio processors and displays.
Industrial Control Systems
In factory automation, this buck converter steps down 24V industrial supplies to 5V or 3.3V for PLCs, motor controllers, and sensors. The 3A output capability supports multiple loads from a single converter.
Telecom and Networking
For networking equipment powered from 12V or 24V backplanes, the ACT4523YH-T offers a reliable solution for generating low-voltage rails for switches, routers, and base stations. The 225kHz frequency provides good efficiency for continuous operation.
Distributed Power Architectures
This device can serve as an intermediate bus converter, stepping down a 24V or 36V rail to an intermediate voltage (e.g., 5V) for downstream POL converters. Its wide input range adds design flexibility.
Battery Charging Systems
In industrial battery chargers, the ACT4523YH-T can regulate the charging voltage from a higher DC bus, providing a controlled output for lead-acid or Li-Ion battery charging circuits.
