DESCRIPTION

FEATURES

•

High efficiency 87%

The SC1633 is a high efficiency step up DC-DC

converter. Only four external components are required

to deliver a fixed voltage of 3V, 3.3V, or 5V. Efficiency

beyond 83% can be easily achieved at 70mA load with

2.2V to 3V input voltages.

Power-saving shutdown mode (7µA typical)

Internal 0.8A switch

120kHz switching rate

Adjustable switch current limit

On-chip low battery detector

A logic-controlled shutdown mode is provided for

power saving. Switch current limit can be programmed

with a resistor. The low battery detector can be

configured as a linear regulator or a burst mode

controller providing extremely low supply current

operation.

APPLICATIONS

•

Pocket organizers

Electronic dictionaries

Cameras

Pagers

Bar code scanners

LCD displays

A switching rate of 120kHz reduces the inductor size -

inductors of 47µH to 150µH inductance are

recommended for most applications.

Battery backup supplies

Portable instruments
