Description
The AAT1118-T1-T is a 1A, 28V step-down (buck) DC-DC converter from Diodes Incorporated. It features high efficiency (up to 95%), a wide input voltage range (4.5V–28V), and a fixed or adjustable output voltage (down to 0.8V).
Key highlights:
- 1A continuous output current
- 1.5MHz switching frequency (enables small external components)
- Integrated power MOSFETs (reduces PCB footprint)
- Low quiescent current (40µA) for power-saving modes
- Protections: Overcurrent, thermal shutdown, and undervoltage lockout
Ideal for portable devices, IoT, and industrial applications requiring compact, efficient power conversion. Available in a SOT23-5 package for space-constrained designs.
For detailed specs, refer to the datasheet.
