The MAX1954A evaluation board is a test board for demonstrating the application circuit of the MAX1954A buck controller. The evaluation board can generate a 1.5V/5A output from an input voltage of 10.8V~13.2V.
The MAX1954A is a high‑efficiency step‑down DC‑DC converter designed for input voltages from 10.8 V to 13.2 V and delivering a regulated 1.5 V output at up to 5 A. It operates at a fixed 300 kHz switching frequency and achieves up to 90 % efficiency.
Typical application circuits, component selection tables, and design equations are included to help designers integrate the device into power‑management solutions. Pin functions, recommended external components, and supplier part numbers are also listed. This manual is written in Chinese.
