HIGH-EFFICIENCY STEP-UP DC/DC CONVERTER CONTROLLER

SPEC NO: DS-1630A-04

ꢀ FEATURES

ꢀ DESCRIPTION

ꢀ Default +5V Output Voltage.

The AIC1630A is a DC-DC converter designed to

ꢀ Adjustable Output Voltage with Two Resistors.

ꢀ Power-Saving Shutdown Mode (7µA typical).

ꢀ 120KHz Switching Rate.

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.

ꢀ On-Chip Low Battery Detector.

ꢀ APPLICATIONS

ꢀ Palmtop & Notebook Computers.

ꢀ Battery Charger Supply.

ꢀ Cellular Telephone.

The output voltage can be internally set to 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.

ꢀ LCD Contrast Supply.

ꢀ Flash Memory Programmer.

ꢀ Battery Backup Supplies.

ꢀ Portable Instruments.

120KHz switching rate reduces the inductor size.

Inductors of 25µH to 50µH inductance are

recommended for most applications.
