MAX77596 - Buck Converter

Description

The MAX77596 is a small, synchronous buck converter with integrated switches.

The device is designed to deliver up to 300mA with input voltages from 3.5V to 24V, while using only 1.1µA quiescent current at no load (fixed-output version).

Features

  • Flexible Power for Systems That Require a Wide Input Voltage Range.
  • VIN Range: 3.5V to 24V.
  • Up to 300mA Output Current.
  • Fixed 3.3V or Programmable 1V to 10V Output Voltage.
  • 98% (Max) Duty Cycle Operation with Low Dropout.
  • Operates from 5V, 12V, or 20V USB Type-C Input Power.
  • Operates from 2S, 3S, or 4S Li-Ion Battery.
  • Minimizes Power Consumption and Extends Battery Life.
  • 1.1µA Quiescent Current (3.3V Fixed Output Voltage).

MAX77596 EVALUATION KIT AVAILABLE 24V, 300mA, Buck Converter with 1.1µA IQ General Description The MAX77596 is a small, synchronous buck converter with integrated switches. The device is designed to deliver up to 300mA with input voltages from 3.5V to 24V, while using only 1.1µA quiescent current at no load (fixed-output version). Voltage quality can be monitored by observing the RESET signal. The device can operate near dropout by running at 98% duty cycle, making it ideal for battery-powered applications. The device offers a fixed 3.3V output version, as well as an adjustable version. The adjustable version allows the user to program the output voltage between 1V and 10V by using a resistor-divider. Frequency is fixed at 1.
