The ACT4525YH from Qorvo is a robust, 3.5A synchronous Buck converter with a fixed 5.1V output. It is designed to operate from a wide input voltage range of 4.5V to 36V, making it exceptionally tolerant of input transients and voltage variations. With a 125kHz switching frequency, it offers a good balance of efficiency and cost-effectiveness. The 8-SOIC package with an exposed pad ensures excellent thermal performance, making it a dependable choice for automotive, industrial, and networking power supplies.
- High Input Voltage Tolerance: Handles up to 36V, providing excellent robustness against voltage spikes in automotive and industrial environments.
- Fixed 5.1V Output: Simplifies design by eliminating the need for external feedback resistors, ideal for USB and logic power.
- High Output Current: Delivers up to 3.5A, sufficient for charging multiple devices or powering moderate loads.
- Cost-Effective Solution: The 125kHz switching frequency allows for the use of lower-cost, larger inductors, reducing overall system cost.
Automotive USB Charging Ports
The 36V input tolerance and fixed 5.1V output make it ideal for automotive USB power ports, providing a stable 5V supply for charging smartphones and tablets directly from the car battery.
Industrial 24V to 5V Conversion
With a wide 4.5V to 36V input range, it can efficiently step down standard 24V industrial control voltages to a regulated 5.1V rail for sensors, PLCs, and HMI panels.
Networking and PoE Powered Devices
For Power over Ethernet (PoE) applications, the ACT4525 can convert the 48V PoE input (after a front-end) down to a 5V logic rail, powering IP cameras, wireless access points, and VoIP phones.
Home Appliances and White Goods
Its ability to handle high input voltage transients makes it suitable for appliances, where it can provide a reliable 5V supply for control boards and user interfaces.
General-Purpose 5V Power Supply
As a robust, fixed-output buck converter, it serves as a simple and reliable power solution for any application requiring a 5V rail from a higher-voltage source.
