APW7137BI-TRG

The APW7137BI-TRG is a high-efficiency, synchronous step-down DC-DC converter from Diodes Incorporated. It operates over a 4.5V to 18V input range and delivers up to 3A output current with adjustable output voltage.
Key features include:
- High efficiency (up to 95%) with integrated MOSFETs.
- Fixed 500kHz switching frequency for stable performance.
- Low quiescent current (30µA) in light-load mode.
- Protections: Over-current (OCP), thermal shutdown (TSD), and under-voltage lockout (UVLO).
Compact and versatile, it comes in a TSOT26 package, making it ideal for space-constrained applications like consumer electronics, networking, and industrial systems.
