AIC1633

2-Cell, 200mA, Step-Up DC/DC Converter

ꢀ FEATURES

ꢀ DESCRIPTION

ꢀ High Efficiency Up To 87%.

The AIC1633 is a high efficiency step up DC/DC

ꢀ Adjustable Output Voltage with Two Resistors

converter. Only four external components are

required to deliver a fixed voltage of 3V, 3.3V, or

5V. The output voltage can be externally set to

an arbitrary value below breakdown voltage of

the power switch for AIC1633A. Efficiency

beyond 83% can be easily achieved at 70mA

load with 2.2V to 3V input voltages.

(AIC1633A)

ꢀ Power-Saving Shutdown Mode (7µA typical).

ꢀ Internal 0.8A Switch.

ꢀ 120KHz Switching Rate.

ꢀ Adjustable Switch Current Limit.

ꢀ On-Chip Low Battery Detector.

ꢀ APPLICATIONS

ꢀ Pocket Organizers.

ꢀ Electronic Dictionaries.

ꢀ Cameras.

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 performing an

extremely low supply current operation.

ꢀ Pagers.

ꢀ Bar-Code Scanners.

ꢀ LCD Displays.

ꢀ Battery Backup Supplies.

ꢀ Portable Instruments.

120KHz switching rate reduces the inductor size.

Inductors of 47µH to 150µH inductance are

recommended for most applications.
