The Alpha & Omega Semiconductor AOZ2151PQI-03 is a synchronous buck converter that steps down 6.5V to 28V inputs to an adjustable 0.8V to 23.8V output. It delivers up to 4A of continuous current at a fixed 1MHz switching frequency. The 18-PowerWFQFN package is ideal for industrial, networking, and automotive power supplies requiring high efficiency and compact size.
- Wide Input Range (6.5V-28V): Handles 12V and 24V rails with margin for transients.
- 4A Output Current: Supports high-power loads for FPGAs and processors.
- 1MHz Switching Frequency: Enables small external components for compact designs.
- Adjustable Output (0.8V-23.8V): Flexible for various logic and analog rails.
Industrial Power Supplies
Convert 24V industrial bus voltages down to 3.3V or 5V for microcontrollers and sensors. The 28V maximum input handles transient spikes, while 4A output supports multiple peripheral loads.
Networking Equipment
Power FPGAs, ASICs, and DDR memory from a 12V intermediate bus. The 1MHz switching frequency allows small inductors and capacitors, reducing board footprint in high-density switch designs.
Automotive Infotainment
Step down 12V car batteries to supply audio processors and display drivers. The wide 6.5V-28V input range accommodates cold-crank and load-dump conditions.
Point-of-Load (POL) Converters
Generate low-voltage rails (0.8V-1.8V) for high-current digital cores. The 4A capability and fast transient response ensure stable operation during dynamic load changes.
Base Station Power
Provide regulated 5V or 3.3V from 24V telecom rectifiers. The high efficiency at 1MHz reduces thermal stress in sealed outdoor enclosures.
Test and Measurement
Supply precision analog and digital circuits from a single 12V input. The adjustable output down to 0.8V enables low-voltage logic and sensor interfaces.
