AX5503 - MICROPOWER VFM STEP-UP DC/DC Converter

Description

The AX5503 is a high efficiency VFM Step-up DC/DC converter for small, low input voltage or battery powered systems with ultra low quiescent supply current.

The AX5503 accept a positive input voltage from start-up voltage to VOUT and convert it to a higher output voltage in the 2.2V to 5V range.

Features

  • Very Low Supply Current is 22uA (typ. ) Maximum shutdown current.

AX5503 MICROPOWER VFM STEP-UP DC/DC Converter  GENERAL DESCRIPTION The AX5503 is a high efficiency VFM Step-up DC/DC converter for small, low input voltage or battery powered systems with ultra low quiescent supply current. The AX5503 accept a positive input voltage from start-up voltage to VOUT and convert it to a higher output voltage in the 2.2V to 5V range. The AX5503 combine ultra low quiescent supply current and high efficiency to give maximum battery life. The high switching frequency and the internally limited peak inductor current permits the use of small, low cost inductors. Only three external components are needed an inductor a diode and an output capacitor.
