EA3059QDR

The EA3059QDR is a high-efficiency, synchronous buck converter from Texas Instruments (TI). It operates over a 4.5V to 18V input range and delivers up to 5A output current with adjustable output voltage.
Key features:
- High efficiency (up to 95%) with integrated MOSFETs.
- 600kHz switching frequency, enabling compact designs.
- Adjustable soft-start and power-good indicator for robust power sequencing.
- Thermal shutdown and overcurrent protection for reliability.
Applications include industrial systems, networking equipment, and point-of-load (POL) power supplies. Its QDR package (3.5mm × 3.5mm) saves board space, making it ideal for space-constrained designs.
For detailed specs, refer to the TI datasheet (SLUSBQ5).
