MAX77813

5.5V Input, 2A, High-Eﬃciency

Buck-Boost Converter

General Description

Features and Beneﬁts

The MAX77813 is a high-efficiency step-up/step-down

(buck-boost) converter targeted for single-cell Li+/Li-ion

battery powered applications. The device maintains a

regulated output voltage from 2.6V to 5.14V across an

input voltage range of 2.3V to 5.5V. The device supports

up to 2A of output current in boost mode and up to 3A in

buck mode.

● V Range: 2.30V to 5.5V

● V

Range: 2.60V to 5.14V

OUT

(I C Programmable in 20mV Steps)

● Up to 2A Output Current in Boost Mode

(V = 3.0V, V

= 3.4V, ILIM = High)

OUT

● Up to 3A Output Current in Buck Mode (ILIM = High)

● Up to 97% Peak Efficiency

The device seamlessly transitions between buck and

boost modes. A unique control algorithm allows high-

efficiency, outstanding load, and line transient response.

● SKIP Mode for Optimal Light Load Efficiency

● 55µA (Typ) Low Quiescent Current

Dedicated enable and power-OK pins allow simple hard-

● Power-OK Output

dynamic voltage scaling, system power optimization, and

fault read-back. The device supports two inductor current

limit options selected by the ILIM pin.

● 2.5MHz Switching Frequency

The MAX77813 is available in a 20-bump, 1.83mm x

2.13mm wafer-level package (WLP).

● Protection Features

• Soft-Start

• Thermal Shutdown

• Overvoltage Protection

• Overcurrent Protection

Applications

● Single-Cell Li+/Li-ion Battery Powered Devices

● Handheld Scanners, Mobile Payment Terminals,

Security Cameras

● 1.827mm x 2.127mm, 20-Bump WLP

● AR/VR Headsets
