The MAX17506 high-efficiency, high-voltage, synchronous step-down DC-DC converter with integrated high-side MOSFET operates over a 4.5V to 60V input. The converter can deliver up to 5A and generates output voltages from 0.9V up to 0.9 x VIN. The feedback (FB) voltage is accurate to within ±1.4% over -40°C to +125°C. The MAX17506 uses peak current-mode control and can be operated in the pulse-width modulation (PWM), pulse-frequency modulation (PFM), and discontinuous conduction mode (DCM) control schemes..

This document describes the hardware shown in Figure 1. It provides a detailed systematic technical guide for the design of buck converter using the MAX17506 for low voltage and smaller size. Refer to the MAX17506 IC data sheet and MAX17506A EV kit data sheet for device operation details. The converter design has been built and tested, details of which follow later in this document.
