The Qorvo ACT4070BYH-T is a versatile synchronous Buck DC-DC converter capable of delivering up to 3A of output current. It operates from a wide input voltage range of 6V to 30V, making it suitable for automotive, industrial, and battery-powered applications. The output voltage is adjustable from 0.808V to 12V, providing flexibility for various logic and peripheral voltages. With a fixed 300kHz switching frequency, this converter offers a good balance between efficiency and component size. The 8-SOIC package with exposed pad enhances thermal performance, ensuring reliable operation in space-constrained designs.
- High Efficiency: Synchronous rectification minimizes power losses, extending battery life in portable applications.
- Wide Input Range (6V-30V): Handles automotive load dumps and industrial 24V rails with margin.
- 3A Output Capability: Powers multiple loads or high-current devices from a single regulator.
- 300kHz Switching Frequency: Allows for smaller inductor and capacitor values, reducing board space and BOM cost.
- Adjustable Output (0.808V-12V): Supports both low-voltage cores and higher-voltage I/O rails.
Battery-Powered Portable Devices
With a 6V to 30V input range and 3A output, the ACT4070BYH-T efficiently regulates power from multi-cell Li-ion batteries or 12V adapters in portable instruments, medical devices, and handheld terminals.
Automotive Infotainment Systems
Operating from a 12V car battery (with transients up to 30V), this buck converter provides a stable 3A supply for infotainment head units, navigation systems, and dashboard displays, ensuring reliable operation under cranking conditions.
Distributed Power Systems
In telecom and server racks, the ACT4070BYH-T converts 12V or 24V intermediate bus voltages down to 5V, 3.3V, or lower for line cards, storage drives, and control logic, with 300kHz switching for compact magnetics.
Industrial Sensor Interfaces
Industrial sensors and transmitters often require clean, isolated power. This converter can step down from 24V field supplies to power microcontrollers, ADCs, and communication interfaces, improving measurement accuracy.
Consumer Electronics
For gaming consoles, set-top boxes, and home appliances, the ACT4070BYH-T offers a cost-effective, high-efficiency solution to generate multiple low-voltage rails from a single 12V or 19V adapter input.
LED Display Panels
The adjustable output up to 12V and 3A current capability make it suitable for driving LED strips and display backlighting, where constant voltage regulation is needed across varying input sources.
