MAX17505 - 1.7A Synchronous Step-Down DC-DC Converter

General Description

The MAX17505/MAX17505S high-efficiency, highvoltage, 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.

Key Features

  • a peak-current-mode control architecture with a MODE feature that can be used to operate the device in pulse-width modulation (PWM), pulse-frequency modulation (PFM), or discontinuousconduction mode (DCM) control schemes. PWM operation provides constant frequency operation at all loads, and is useful in.

MAX17505 EVALUATION KIT AVAILABLE 4.5V-60V, 1.7A, High-Efficiency, Synchronous Step-Down DC-DC Converter With Internal Compensation General Description The MAX17505/MAX17505S high-efficiency, highvoltage, 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 -40NC to +125NC is ±1.1%. The device is available in a compact (4mm x 4mm) TQFN lead(Pb)-free package with an exposed pad. Simulation models are available.
