AIC1638

3-PIN ONE-CELL STEP-UP DC/DC CONVERTER

SPEC NO: DS-1638-00 03/01/00

FEATURES

DESCRIPTION

Guaranteed Start-Up from below 0.9 V.

High Efficiency.

The AIC1638 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, or

5V. The AIC1638 starts up from below 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

ripple and noise are lower compared with the circuits

operating in PSM mode.

Low Quiescent Current.

Few Number of External Components needed.

Low Ripple and Low Noise.

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

Space Saving SOT-89 and TO-92 Packages.

ꢀ

APPLICATIONS

Pagers.

Cameras.

Wireless Microphones.

Pocket Organizers.

Battery Backup Suppliers.

Portable Instruments.

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 AIC1638 an ideal choice of

DC/DC converter

for space conscious

applications, like pagers, electronic cameras, and

wireless microphones
