Introduction

AI Translation

The MAX17505/MAX17505S high-efficiency, high-voltage, synchronously rectified step-down converter with dual integrated MOSFETs operates over a 4.5V to 60V input. It delivers up to 1.7A and 0.9V to 90%VIN output voltage. Built-in compensation across the output voltage range eliminates the need for external components. The feedback (FB) regulation accuracy over -40℃ to +125℃ is ±1.1%. The device is available in a compact 4mm×4mm TQFN lead(Pb)-free package with an exposed pad. Simulation models are available.

Features

AI Translation
  • Peak-current-mode control architecture with a MODE feature for PWM, PFM, or DCM control schemes
  • PWM operation provides constant frequency at all loads
  • PFM operation disables negative inductor current and skips pulses at light loads for high efficiency
  • DCM features constant frequency operation down to lighter loads than PFM mode, disabling negative inductor current at light loads
  • MAX17505S offers a lower minimum on-time for higher switching frequencies and smaller solution size
  • Programmable soft-start feature to reduce input inrush current
  • Output enable/undervoltage lockout pin (EN/UVLO) to turn on the part at the desired input voltage level
  • Open-drain RESET pin provides a delayed power-good signal upon successful output voltage regulation

Applications

AI Translation
  • Industrial Power Supplies
  • Distributed Supply Regulation
  • Base Station Power Supplies
  • Wall Transformer Regulation
  • High-Voltage Single-Board Systems
  • General-Purpose Point-of-Load
