MAX867 - 3.3V/5V or Adjustable-Output / Single-Cell DC-DC Converters

General Description

The MAX866 and MAX867 are ultra-small, high-efficiency, CMOS, step-up, DC-DC switching regulators for 1-cell battery-powered systems.

The MAX866 accepts a positive input voltage between 0.8V and VOUT and converts it to a higher, pin-selectable output voltage of 3.3V or 5V.

Key Features

  • o 0.8V to 6.0V Input Supply Voltage o 0.9V Guaranteed Start-Up Supply Voltage o >80% Efficiency Over Wide Load Range o 100µA No-Load Battery Current (VOUT = 3.3V) o 1µA Shutdown Mode o Up to 250kHz Switching Frequency o ±1.5% Reference Tolerance o Low-Battery Detector (LBI/LBO) o Available in Ultra-Small 8-Pin µMAX Package (1.11mm high) o Circuit Fits in 0.2in2 _______________General.
