描述

The MAXREFDES1274 is a buck converter using the MAX17501F high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated MOSFETs and internal compensation. This design produces a 5V output at up to 500mA from a wide input range of 6.5V to 60V. The device features peak-current-mode control with pulse-width modulation (PWM). The MAXREFDES1274 was optimized for small solution size and is laid out on a two-layer PC board.
