AX5502 - MICROPOWER VFM STEP-UP DC/DC Converter

Description

The AX5502 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 AX5502 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 Regulated Output Voltage Wide range of output voltage is available form 2.2V to 5.0V by 0.1V steps Output Voltage Accuracy ±5% Output Current up to 100mA Low ripple and low noise Very low start-up voltage High efficiency (VOUT = 5V TYP. 87%) Few external components Low profile: SOT-23-3L, SOT-23-5L and SOT-89-3L Pb-Free 1/11 Axelite Confidential Materials, do not copy or distribute without written consent.

AX5502 MICROPOWER VFM STEP-UP DC/DC Converter  GENERAL DESCRIPTION The AX5502 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 AX5502 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 AX5502 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.
