Product Overview

The MAX856ESA+ is a 3.3V/5V output, step up DC to DC converter in 8 pin NSOIC package. It is a high-efficiency, CMOS, step up DC to DC switching regulator for small, low input voltage or battery-powered systems. The MAX856/MAX858 accept a positive input voltage between 0.8V and VOUT and convert it to a higher pin-selectable output voltage of 3.3V or 5V. Typical efficiency is greater than 85%. It combines ultra-low quiescent supply current and high efficiency to give maximum battery life. An internal MOSFET power transistor permits high switching frequencies. This benefit, combined with internally set peak inductor current limits, permits the use of small, low-cost inductors. This device is used in 3.3V to 5V step-up conversion, palmtop computers, personal data communicators/computers, medical instrumentation, 2cell & 3cell battery-operated equipment and glucose meters.
  • Input supply voltage range from 0.8V to 6V
  • Start-up supply voltage range from 0.8V
  • Quiescent current is 25µA
  • Shutdown mode current is 1µA
  • 500mA peak inductor current limit
  • Switching frequency is 500KHz
  • 1.5% reference tolerance over temperature
  • Low battery detector (LBI/LBO)
