SS6638G

Simple 3-Pin Step-Up DC/DC Converter

FEATURES

DESCRIPTION

Guaranteed start-up from less than 0.9 V.

The SS6638G is a high-efficiency step-up DC/DC

converter for applications using 1 to 4 NiMH

battery cells. Only three external components are

required to deliver a fixed output voltage of 2.7V,

3.0V, 3.3V, 4.5V or 5V. The SS6638G starts up

from less than 0.9V input with 1mA load. A Pulse

Frequency Modulation scheme brings optimized

performance for applications with light output

loading and low input voltages. The output ripple

and noise are lower compared with circuits

operating in PSM mode.

High efficiency.

Low quiescent current.

Fewer external components needed.

Low ripple and low noise.

Fixed output voltage: 2.7V, 3.0V, 3.3V, 4.5V

and 5V.

Space saving packages: SOT-23, SOT-89

and TO-92.

Pb-free, RoHS compliant.

APPLICATIONS

Pagers.

The PFM control circuit operating at a maximum

100kHz switching rate results in smaller passive

components. The space saving SOT-23, SOT-89

and TO-92 packages make the SS6638G an ideal

choice of DC/DC converter for space-conscious

applications, like pagers, electronic cameras, and

wireless microphones.

Cameras.

Wireless Microphones.

Pocket Organizers.

Battery Backup Supplies.

Portable Instruments.
