The ACT4523AYH-T from Qorvo is a synchronous step-down (buck) DC-DC converter designed for high-current applications. It accepts an input voltage from 10V to 36V and provides an adjustable output from 0.808V to 12V, delivering up to 3.5A. The fixed 250kHz switching frequency offers a good trade-off between efficiency and external component size. Housed in an 8-SOIC exposed pad package, it is suitable for automotive, industrial, and networking power supplies.
- High Output Current: Delivers up to 3.5A, suitable for powering FPGAs, processors, and other high-current loads.
- Wide Input Voltage Range: 10V to 36V covers 12V and 24V systems, including automotive transients.
- Thermally Enhanced Package: The exposed pad in the 8-SOIC package improves heat dissipation, enhancing reliability in demanding environments.
- Stable Fixed Frequency: 250kHz switching frequency simplifies EMI filtering and allows predictable design.
Automotive Power Systems
The ACT4523AYH-T's 10V to 36V input range makes it ideal for automotive applications such as infotainment systems, ADAS sensors, and body control modules. It can handle 12V battery voltage and withstand load-dump transients up to 36V, providing a stable 3.3V or 5V rail.
Industrial Power Supplies
In industrial automation and control systems, this buck converter converts 24V DC bus voltages down to logic levels (e.g., 5V, 3.3V) with up to 3.5A output. The 250kHz frequency balances efficiency and component size for 24V industrial environments.
Networking Equipment
For routers, switches, and base stations powered from 12V or 24V supplies, the ACT4523AYH-T provides a high-current, low-voltage rail for FPGAs, ASICs, and DDR memory. The exposed pad package aids thermal dissipation in continuous operation.
Point-of-Load (POL) Converters
This device can be used as a POL converter in distributed power architectures, stepping down an intermediate bus voltage (e.g., 12V or 24V) to a precise core voltage. The adjustable output down to 0.808V supports modern low-voltage digital ICs.
LED Lighting Drivers
With its wide input range and 3.5A capability, the ACT4523AYH-T can drive high-power LED strings in industrial or commercial lighting, using a constant-current configuration with external components.
