MAX20059

72V, 1A, Automotive Synchronous Step-Down DC-DC Converter

72V Synchronous Buck Converter with Internal FETs Enables High Efficiency and Low Temperature Rise

Data Sheet

Please check latest availability status for a specific part variant.

Overview

Description

The MAX20059 is a high-efficiency, high-voltage, synchronous step-down DC-DC converter IC with integrated MOSFETs that operates over a 4.5V to 72V input. The converters can deliver up to 1A current. Output voltage is programmable from 0.8V to 90%V_IN. The feedback voltage-regulation accuracy over -40°C to +125°C is ±1.5%.

The IC features a peak-current-mode-control architecture and can be operated in the pulse-width modulation (PWM) or pulse-frequency modulation (PFM) control schemes.

The MAX20059 is available in a 12-pin (3mm x 3mm) side-wettable TDFN package with an exposed pad for thermal heat dissipation.
