AIC1610/AIC1611

High Efficiency Synchronous Step-Up DC/DC

Converter

DESCRIPTION

ꢀ

FEATURES

ꢀ

High Efficiency (93% when V_IN=2.4V,

ꢁ

The AIC1610/AIC1611 are high efficiency

step up DC-DC converters. The start-up volt-

age is as low as 0.8V with operating voltage

down to 0.7V. Simply consuming 20µA of qui-

escent current. These devices offer a built-in

synchronous rectifier that reduces size and

cost by eliminating the need for an external

Schottky diode and improves overall effi-

ciency by minimizing losses.

_OUT=3.3V, I_OUT=200mA)

Output Current up to 500mA. (AIC1610 at

V_IN=2.4V and V_OUT=3.3V)

ꢁ

20µA Quiescent Supply Current.

ꢁ

Power-Saving Shutdown Mode (0.1µA typical).

Internal Synchronous Rectifier (No External Di-

ode Required).

On-Chip Low Battery Detector.

Low Battery Hysteresis

ꢁ

Space-Saving Package: MSOP-8

The switching frequency can range up to

500KHz depending on the load and input volt-

age. The output voltage can be easily set by

two external resistors from 1.8V to 5.5V,

connecting FB to OUT to get 3.3V, or con-

necting to GND to get 5.0V. The peak current

of the internal switch is fixed at 1.0A (AIC1610)

or 0.65A (AIC1611) for design flexibility.
