MAX5080/MAX5081

1A, 40V, MAXPower Step-Down

DC-DC Converters

General Description

Features

● 4.5V to 40V (MAX5080) or 7.5V to 40V (MAX5081)

Input Voltage Range

The MAX5080/MAX5081 are 250kHz PWM step-down

DC-DC converters with an on-chip, 0.3Ω high-side switch.

The input voltage range is 4.5V to 40V for the MAX5080

and 7.5V to 40V for the MAX5081. The output is adjustable

from 1.23V to 32V and can deliver up to 1A of load current.

● 1A Output Current

● V

Range From 1.23V to 32V

OUT

● Internal High-Side Switch

Both devices utilize a voltage-mode control scheme for

good noise immunity in the high-voltage switching environ-

ment and offer external compensation allowing for maxi-

mum flexibility with a wide selection of inductor values and

capacitor types. The switching frequency is internally fixed

at 250kHz and can be synchronized to an external clock

signal through the SYNC input. Light load efficiency is

improved by automatically switching to a pulse-skip mode.

● Fixed 250kHz Internal Oscillator

● Automatic Switchover to Pulse-Skip Mode at Light

Loads

● External Frequency Synchronization

● Thermal Shutdown and Short-Circuit Protection

● Operates Over the -40°C to +125°C Temperature

Range

All devices include programmable undervoltage lock-

out and soft-start. Protection features include cycle-

by-cycle current limit, hiccup-mode output short-circuit

protection, and thermal shutdown. Both devices are

available in a space-saving, high-power (2.7W), 16-pin

TQFN package and are rated for operation over the

-40°C to +125°C temperature range.
