Product Overview

The MAX17504ATP+ is a 4.5V to 60V, 3.5A, high-efficiency, synchronous step-down DC to DC converter with internal compensation in 20 pin TQFN package. It delivers up to 3.5A and 0.9V to 90% VIN output voltage. Built-in compensation across the output voltage range eliminates need for external components. It features a peak-current-mode control architecture with a MODE feature that can be used to operate the device in pulse-width modulation, pulse-frequency modulation or discontinuous mode control schemes. PWM operation provides constant frequency operation at all loads and is useful in applications sensitive to switching frequency. PFM operation disables negative inductor current and additionally skips pulses at light loads for high efficiency. DCM features constant frequency operation down to lighter loads than PFM mode, by not skipping pulses, but only disabling negative inductor current at light loads. DCM operation offers efficiency performance that lies between PWM and PFM modes.
  • Supply voltage range is 4.5V to 60V
  • Operating temperature range from -40°C to 125°C
  • No schottky synchronous operation for high efficiency and reduced cost
  • Internal compensation for stable operation at any output voltage
  • 200KHz to 2.2MHz adjustable frequency with external synchronization
  • Shutdown current is 2.8µA (typ)
  • Hiccup-mode current limit and autoretry start-up
  • Adjustable soft-start and pre-biased power-up
  • Resistor programmable EN/UVLO threshold
  • Built-in output voltage monitoring
