LM2705 - Micropower Step-Up DC/DC Converter

Description

The LM2705 is a micropower step-up DC-DC converter in a small 5-pin SOT-23 package.

A current-limited, fixed-off-time control scheme conserves operating current, which results in high efficiency over a wide range of load conditions.

The 21-V switch allows for output voltages as high as 20 V.

Features

  • 1 2.2-V to 7-V Input Range.
  • 150-mA, 0.7-Ω Internal Switch.
  • Adjustable Output Voltage up to 20 V.
  • Input Undervoltage Lockout.
  • 0.01-µA Shutdown Current.
  • Uses Small Surface-Mount Components.
  • Small 5-Pin SOT-23 Package 2.
