产品概述

The MAX5090CATE+ is a 2A, 76V, high-efficiency MAXPower step-down DC to DC converter in 16 pin TQFN package. It is an easy to use, high-efficiency, high voltage step-down DC-DC converters operate from an input voltage up to 76V and consume only 310µA quiescent 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 current and high efficiency at light loads. The MAX5090 includes internal frequency compensation simplifying circuit implementation. The device can also be synchronized 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 under voltage lockout, cycle by cycle current limit, hiccup-mode output short-circuit protection and overtemperature shutdown.
  • Supply voltage range is 6.5V to 76V
  • Operating temperature range from -40°C to 125°C
  • Output current is 2A
  • Adjustable 1.265V to 11V output voltage
  • Efficiency up to 92%
  • Internal 0.26ohm high-side DMOSFET
  • Quiescent current is 310µA at no load
  • Shutdown current is 19µA
  • Internal frequency compensation and external frequency synchronization
  • Capable of dissipating 2.67W at +70°C
