AIC1630

2-Cell, Step-Up DC/DC Converter Controller

ꢀ FEATURES

ꢀ DESCRIPTION

ꢀ Adjustable Output Voltage with Two Resistors

(AIC1630A).

The AIC1630 is a DC-DC converter designed to

drive an external power switch for more flexibility,

especially in higher voltage and larger power

applications. Typically six components are

required to set up a step up configuration easily

achieving efficiency beyond 80%. A few more

components are required to set up a step down

configuration delivering 4A load current with 83%

typical efficiency, 86% at 2A load, and 300µA

quiescent current.

ꢀ Power-Saving Shutdown Mode (7µA typical).

ꢀ 120KHz Switching Rate.

ꢀ On-Chip Low Battery Detector.

ꢀ APPLICATIONS

ꢀ Palmtop & Notebook Computers.

ꢀ Battery Charger Supply.

ꢀ Cellular Telephone.

ꢀ LCD Contrast Supply.

ꢀ Flash Memory Programmer.

ꢀ Battery Backup Supplies.

ꢀ Portable Instruments.

The output voltage is internally set to 3V, 3.3V, 5V

or externally set to an arbitrary value below

breakdown voltage of the power switch. Logic-

controlled shutdown mode is provided for power

saving. The low battery detector can be also

configured as a linear regulator.

120KHz switching rate reduces the inductor size.

Inductors of 25µH to 50µH inductance are

recommended for most applications.
