MAX5082/MAX5083

1.5A, 40V, MAXPower Step-Down

DC-DC Converters

General Description

Features

● 4.5V to 40V (MAX5082) or 7.5V to 40V (MAX5083)

Input Voltage Range

The MAX5082/MAX5083 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

MAX5082 and 7.5V to 40V for the MAX5083. The output

is adjustable from 1.23V to 32V and can deliver up to

1.5A of load current.

● 1.5A Output Current

● V

Range From 1.23V to 32V

OUT

● Internal High-Side Switch

● Fixed 250kHz Internal Oscillator

Both devices utilize a voltage-mode control scheme for

good noise immunity in the high-voltage switching envi-

ronment and offer external compensation allowing for

maximum 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.

● 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

● Space-Saving (5mm x 5mm) High-Power 16-Pin

TQFN Package

All devices include programmable undervoltage lockout and

soft-start. Protection features include cycle-bycycle current

limit, hiccup-mode output short-circuit protection, and ther-

mal 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.
