The AT8028 from Analog Technologies is a versatile, synchronous step-down DC-DC converter offering an adjustable output from 0.6V to 5.5V. It accepts an input voltage between 2.6V and 5.5V and delivers up to 1.5A of continuous current. Operating at a fixed 2MHz switching frequency, it enables a compact design with small inductors and capacitors. This buck converter is well-suited for battery-powered equipment, point-of-load regulation, and portable devices requiring high efficiency and design flexibility.
- Adjustable Output Flexibility: Output can be set from 0.6V to 5.5V, supporting a wide range of logic and core voltages.
- High Output Current: 1.5A capability handles demanding loads in portable and industrial applications.
- Compact Package: The SOT-753 package is ideal for space-limited designs.
- Stable 2MHz Operation: Reduces external component size and improves transient response.
Portable Electronics with Variable Core Voltages
The adjustable output from 0.6V to 5.5V makes the AT8028 suitable for powering FPGAs, DSPs, and microcontrollers that require dynamic voltage scaling for power optimization.
Battery-Powered Handheld Devices
With a 2.6V to 5.5V input range and 1.5A output capability, it efficiently regulates power from a single Li-Ion or Li-Poly cell for applications like GPS units and portable media players.
Industrial Sensor Interfaces
The 2MHz switching frequency allows for small external components, making it ideal for compact industrial sensors that need a stable, adjustable supply from a 3.3V or 5V bus.
Networking Equipment
Provides a clean, adjustable power rail for low-voltage logic in routers and switches, ensuring reliable operation from standard 5V supplies.
USB-Powered Devices
Can step down the 5V USB bus to lower voltages (e.g., 1.8V, 2.5V, 3.3V) for peripheral devices, with up to 1.5A for power-hungry components.
