MICROPOWER VFM STEP-UP DC/DC CONVERTER

FEATURES

DESCRIPTION

The APE2903 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

Very Low Supply Current

Regulated Output Voltage

Wide Range of Output Voltage is Available from

2.2V to 5.0V by 0.1V Steps

APE2903 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.

Output Voltage Accuracy ±5%

The APE2903 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.

The APE2903 is suitable to be used in battery powered

equipment where low noise, low ripple and ultra low supply

current are required. The APE2903 is available in very small

package:

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, SOT-89 & SOT-23-5L Pb-Free

SOT-23, SOT-89 & SOT-23-5L.

Typical applications are pagers, cameras & video

camera, cellular telephones, wireless telephones, palmtop

computer, battery backup supplies, battery powered

equipment.
