MAX77596

24V, 300mA, Buck Converter with 1.1µA I

General Description

Beneﬁts and Features

● Flexible Power for Systems That Require a Wide

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.

Input Voltage Range

• V Range: 3.5V to 24V

• Up to 300mA Output Current

• Fixed 3.3V, 5V, 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

The device offers fixed 3.3V and 5V output versions, 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

1.7MHz, which allows for small external components and

reduced output ripple. The device offers both forced-PWM

and skip modes of operation, with ultra-low quiescent cur-

rent of 1.1µA in skip mode.

● Minimizes Power Consumption and Extends Battery

Life

• 1.1µA Quiescent Current (3.3V Fixed Output

Voltage)

• 86% Peak Efficiency at 12V , 3.3 V

OUT

The MAX77596 is available in a small (2mm x 2.5mm)

10-pin TDFN package and operates across the -40°C to

+85°C temperature range.

● Minimizes Solution Size

• 1.7MHz Operating Frequency

• Small 2.0mm x 2.5mm x 0.75mm 10-Pin TDFN

Package

Applications

● Portable Devices Powered from 2s, 3s,

or 4s Li+ Batteries

● USB Type-C Devices

● Robust Solution

• Short-Circuit, Thermal Protections

• 6.67ms Internal Soft-Start Minimizes Inrush Current

• Current-Mode Control Architecture

• Up to 42V Input Voltage Tolerance

● Point-of-Load Applications
