The Alpha & Omega Semiconductor AOZ2151PQI-10 is a synchronous buck converter designed for 12V to 28V input applications. It provides an adjustable output from 0.8V to 23.8V with up to 4A of continuous current. Operating at a fixed 1MHz, it enables compact power solutions for automotive, industrial, and telecom systems.
- Optimized for 12V Input: Ideal for standard 12V intermediate bus architectures.
- 4A Continuous Output: Handles high-current loads with minimal voltage droop.
- 1MHz Fixed Frequency: Reduces output ripple and external component size.
- Wide Output Range (0.8V-23.8V): Supports both low-voltage cores and higher-voltage peripherals.
12V Input POL Converters
Step down 12V server or telecom rails to 1.0V-3.3V for high-current digital loads. The 4A output and 1MHz frequency optimize power density in rack-mounted equipment.
Automotive Body Electronics
Convert 12V battery voltage to 5V for infotainment and ADAS sensors. The 28V maximum input provides headroom for load-dump transients.
Industrial Automation
Power PLCs and motor controllers from 24V supplies. The 12V minimum input ensures stable operation with regulated 12V intermediate buses.
LED Lighting Drivers
Drive high-power LED strings from a 12V supply with constant voltage. The adjustable output allows precise current limiting via external resistors.
Communication Infrastructure
Supply 3.3V and 5V rails for baseband processors in 5G small cells. The high efficiency reduces cooling requirements in compact enclosures.
Consumer Electronics
Power gaming consoles and set-top boxes from a 12V adapter. The small 18-PowerWFQFN package fits slim form factors.
