2A, 76V, High-Efficiency

MAXPower Step-Down DC-DC Converters

General Description

Features

♦ Wide Input Voltage Range: 6.5V to 76V

The MAX5090A/B/C easy-to-use, high-efficiency, high-

voltage step-down DC-DC converters operate from an

input voltage up to 76V, and consume only 310µA qui-

escent current at no load. This pulse-width-modulated

(PWM) converter operates at a fixed 127kHz switching

frequency at heavy loads, and automatically switches

to pulse-skipping mode to provide low quiescent cur-

rent and high efficiency at light loads. The MAX5090

includes internal frequency compensation simplifying

circuit implementation. The device can also be syn-

chronized with external system clock frequency in a

noise-sensitive application. The MAX5090 uses an

internal low on-resistance and a high-voltage DMOS

transistor to obtain high efficiency and reduce overall

system cost. This device includes undervoltage lock-

out, cycle-by-cycle current limit, hiccup-mode output

short-circuit protection, and overtemperature shutdown.

♦ Fixed (3.3V, 5V) and Adjustable (1.265V to 11V)

Output-Voltage Versions

♦ 2A Output Current

♦ Efficiency Up to 92%

♦ Internal 0.26Ω High-Side DMOS FET

♦ 310µA Quiescent Current at No Load

♦ 19µA Shutdown Current

♦ Internal Frequency Compensation

♦ Fixed 127kHz Switching Frequency

♦ External Frequency Synchronization

♦ Thermal Shutdown and Short-Circuit Current Limit

♦ -40°C to +125°C Automotive Temperature Range

♦ 16-Pin (5mm x 5mm) Thin QFN Package

♦ Capable of Dissipating 2.67W at +70°C

The MAX5090 delivers up to 2A output current. External

shutdown is included, featuring 19µA (typ) shutdown

current. The MAX5090A/MAX5090B versions have fixed

output voltages of 3.3V and 5V, respectively, while the

MAX5090C features an adjustable 1.265V to 11V output

voltage.
