MAX17501 - Synchronous Step-Down DC-DC Converter

General Description

The MAX17501 high-efficiency, high-voltage, synchro­nous step-down DC-DC converter with integrated MOSFETs operates over a 4.5V to 60V input voltage range.

This device is offered in a fixed 3.3V, 5V, or adjustable output voltage (0.9V to 92%VIN) while delivering up to 500mA of current.

Key Features

  • peak-current-mode control with pulse-width modulation (PWM). Users can choose devices with either pulse frequency modulation (PFM) or forced PWM scheme. PFM devices skip pulses at light load for higher efficiency, while forced-PWM devices operate with fixed switching frequency at any load for noise sensitive.
