The ACT4533AYH-T from Qorvo is a robust synchronous buck DC-DC converter designed for high-voltage industrial and automotive applications. It accepts a wide input voltage from 10V to 38V and provides an adjustable output from 0.808V to 12V with up to 3.5A of continuous current. The fixed 125kHz switching frequency balances efficiency and component size, while the 8-SOIC exposed-pad package ensures excellent thermal performance. This converter is well-suited for automotive systems, industrial power supplies, and networking equipment requiring reliable step-down conversion.
- Wide Input Voltage Range: 10V to 38V input handles automotive transients and industrial 24V rails.
- High Output Current: 3.5A continuous output supports power-hungry loads like FPGAs and motors.
- Thermally Enhanced Package: Exposed pad in 8-SOIC improves heat dissipation for reliable operation at high currents.
- Fixed 125kHz Frequency: Simplifies EMI filtering and provides predictable switching behavior.
Automotive Infotainment Systems
The wide 10V to 38V input range covers automotive load-dump and cold-crank conditions, making the ACT4533A ideal for powering infotainment head units, displays, and telematics from a 12V battery bus.
Industrial Power Supplies
For 24V industrial control systems, this buck converter steps down to a regulated 5V or 3.3V rail for PLCs, motor controllers, and factory automation sensors, with 3.5A capability for multiple loads.
Networking Equipment
In PoE (Power over Ethernet) switches and routers, the ACT4533A converts a 48V input down to a lower voltage for internal logic, leveraging its high input voltage rating and robust current handling.
LED Lighting Drivers
The 125kHz fixed frequency and 3.5A output make it suitable for driving high-power LED arrays in street lighting or architectural lighting, where constant current can be implemented with external components.
Distributed Power Architectures
As an intermediate bus converter, it can step down a 24V or 36V bus to a 12V or 5V intermediate rail, which is then used by point-of-load converters for FPGAs and ASICs in telecom equipment.
Home Appliance Control Boards
In appliances like washing machines or air conditioners, the wide input range accommodates mains rectified voltages, providing a stable low-voltage supply for microcontrollers and user interfaces.
