The Qorvo ACT4533CYH-T is a high-performance synchronous Buck DC-DC converter designed for demanding applications requiring up to 3.5A of output current. It accepts a wide input voltage from 10V to 38V and provides an adjustable output from 0.808V to 18V, making it highly versatile for industrial, networking, and point-of-load designs. Operating at a fixed 125kHz switching frequency, this regulator balances efficiency with reduced switching losses. The 8-SOIC package with exposed pad ensures excellent thermal performance. Its robust feature set simplifies power supply design while delivering reliable, regulated power.
- High Output Current: Delivers up to 3.5A, suitable for powering FPGAs, processors, and high-current peripherals.
- Wide Input Voltage Range: Accepts 10V to 38V, accommodating 12V, 24V, and 36V supply rails in industrial and telecom systems.
- Adjustable Output Flexibility: Output can be set from 0.808V to 18V, supporting both low-voltage logic and higher-voltage loads.
- Low Fixed Frequency (125kHz): Reduces EMI concerns and simplifies filter design in noise-sensitive applications.
- Thermally Enhanced Package: The exposed pad 8-SOIC package improves heat dissipation for reliable operation at full load.
Industrial Power Supplies
With a wide 10V to 38V input range and 3.5A output capability, the ACT4533CYH-T is ideal for industrial control systems, factory automation, and test equipment requiring a stable, high-current step-down conversion from 24V or 36V rails.
Networking and Telecom Equipment
Telecom base stations and networking switches often operate from 24V or 48V backplanes. This buck converter efficiently steps down to lower logic and I/O voltages, supporting high-current loads up to 3.5A with a low 125kHz switching frequency for reduced EMI.
Point-of-Load (POL) Regulation
For distributed power architectures, the ACT4533CYH-T provides a compact POL solution. Its adjustable output down to 0.808V makes it suitable for powering modern low-voltage FPGAs, ASICs, and DSPs from a 12V intermediate bus.
LED Lighting Drivers
The wide output voltage range (up to 18V) and high current capability make this device suitable for driving high-power LED arrays in commercial and industrial lighting, where constant voltage or current-limited operation is required.
Automotive Aftermarket Systems
Although not AEC-Q100 qualified, the 38V maximum input handles 24V truck systems and 12V automotive transients in aftermarket infotainment, telematics, and body control modules, delivering clean power for sensors and microcontrollers.
Battery Charging Systems
In battery-powered equipment, the ACT4533CYH-T can be used as a pre-regulator or charging stage, converting a variable input from solar panels or unregulated adapters into a stable voltage for charging 12V lead-acid or lithium battery packs.
