MAXREFDES1054: Non-Isolated, Single-Output, Synchronous Buck, Step-Down, DC-DC Converter Using the MAX17506

MAXREFDES1054

Reference Design Disclaimer See the  Important Notice and Disclaimer  covering reference designs and other Maxim resources.

Description

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..

Features

  • Wide 4.5V to 60V Input
  • Adjustable 0.9V to 0.9 x VIN Output
  • 100kHz to 2.2MHz Adjustable Switching Frequency with External Synchronization
  • 100kHz to 2.2MHz Adjustable Switching Frequency
  • Up to 5A Output Current
  • Fully Assembled and Tested
  • Proven PCB Layout
