FEATURES

DESCRIPTION

A Guaranteed Start-Up from less than 0.9 V.

The AIC1642 is a high efficiency step-up

DC/DC converter for applications using 1 to 4

battery cells. Only three external components

are required to deliver a fixed output voltage of

2.7V, 3.0V, 3.3V, or 5V. The AIC1642 starts up

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

Frequency Modulation scheme brings optimized

performance for applications with light output

loading and low input voltages. The output rip-

ple and noise are lower compared with the cir-

cuits operating in PSM mode.

High Efficiency.

Low Quiescent Current.

Less Number of External Components needed.

Low Ripple and Low Noise.

Fixed Output Voltage: 2.7V, 3.0V, 3.3V, and 5V.

Space Saving Packages: SOT-89 and TO-92

■ APPLICATIONS

Pagers.

Cameras.

The PFM control circuit operating in 100KHz

(max.) switching rate results in smaller passive

components. The space saving SOT-89 and

TO-92 packages make the AIC1642 is an ideal

choice of DC/DC converter for space conscious

applications, like pagers, electronic cameras,

and wireless microphones.

Wireless Microphones.

Pocket Organizers.

Battery Backup Suppliers.

Portable Instruments.
