MAX5081 - 1A / 40V / MAXPower Step-Down DC-DC Converters

Download the MAX5081 datasheet PDF. This datasheet also covers the MAX5080 variant, as both devices belong to the same 1a / 40v / maxpower step-down dc-dc converters family and are provided as variant models within a single manufacturer datasheet.

General Description

The MAX5080/MAX5081 are 250kHz PWM step-down DC-DC converters with an on-chip, 0.3 Ω 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.

Key Features

  • include cycle-bycycle 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. Features.
  • 4.5V to 40V (MAX5080) or 7.5V to 40V (MAX5081) Input Voltage Range.
  • 1A Output Current.
  • VOUT Range From 1.23V to 32V.
  • Internal High-Side Switch.
  • Fixed 250kHz Internal Oscillator.

19-3656; Rev 1; 2/07 www.DataSheet4U.com 1A, 40V, MAXPower Step-Down DC-DC Converters General Description The MAX5080/MAX5081 are 250kHz PWM step-down DC-DC converters with an on-chip, 0.3 Ω 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. Both devices utilize a voltage-mode control scheme for good noise immunity in the high-voltage switching environment 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.
