The ACT4525YH-T from Qorvo is a buck DC-DC converter that steps down 4.5V to 36V inputs to a fixed 5.1V output. It delivers up to 3.5A of output current with a 125kHz switching frequency. The 8-SOIC exposed pad package is designed for automotive and industrial applications requiring wide input voltage tolerance.
- Wide Input Voltage: 4.5V to 36V range handles automotive load dumps and industrial transients.
- Fixed 5.1V Output: Ideal for USB and logic applications without external feedback resistors.
- High Current Capability: 3.5A supports multiple loads or fast charging.
- Robust Design: Low 125kHz frequency improves noise immunity in harsh environments.
Automotive USB Chargers
Step down 12V or 24V vehicle power to a stable 5.1V for USB charging ports. The 3.5A output supports fast charging of smartphones and tablets.
Industrial Control Systems
Convert 24V or 36V industrial supplies to 5V for PLCs and sensors. The wide input range handles voltage fluctuations.
LED Lighting Drivers
Provide a constant 5.1V rail for LED driver circuits. The 125kHz frequency offers good efficiency for high-voltage step-down.
Point-of-Load Regulation
Use as a local 5V supply from a higher-voltage bus. The fixed output simplifies design and reduces external components.
Home Appliances
Power microcontrollers and displays in appliances from rectified AC rails. The robust 36V input tolerance ensures reliability.
