产品概述

The MAX651ESA+ is a 3.3V or adjustable, high efficiency, low IQ, step-down DC-DC controller in 8 pin NSOIC package. This BiCMOS, controller provides high efficiency over three decades of load current. A unique, current-limited pulse frequency modulated (PFM) control scheme gives device the benefits of pulse width modulation (PWM) converter (high efficiency at heavy loads) while using only 100µA of supply current (vs. 2mA to 10mA for PWM converters). The result is high efficiency over loads ranging from 10mA to more than 2.5A. Device uses miniature external components, its high switching frequency (up to 300KHz) allows for less than 9mm diameter surface-mount inductors. This controller drives external P-channel MOSFETs at loads greater than 10W. If less power is required, use MAX651ESA+ step-down converter with on-chip FETs which allow up to a 225mA load current. It is used in 5V-to-3.3V green PC applications, high efficiency step-down regulation & minimum-component DC-DC converters
  • Supply voltage range is 4V to 16.5V
  • Operating temperature range from -40°C to 85°C
  • More than 90% efficiency (10mA to 1.5A loads)
  • More than 12.5W output power
  • Maximum quiescent supply current is 100µA
  • Maximum shutdown supply current is 5µA
  • Less than 1V dropout voltage
  • Maximum input voltage is 16.5V
  • Current limited control scheme
  • Up to 300KHz switching frequency
