AIC1555

Low-Noise Synchronous PWM Step-Down

DC/DC Converter

ꢀ

DESCRIPTION

ꢀ

FEATURES

The AIC1555 is

a low-noise pulse-width-

95% Efficiency or up

ꢁ

modulated (PWM) DC-DC step-down converter.

It powers logic circuits in PDAs and small

wireless systems such as cellular phones,

handy-terminals.

700mA Guaranteed Output Current.

Adjustable Output Voltage from 0.75V to VIN

of a range from +2.5V to 6.5V.

Very Low Quiescent Current: 35µA (Typ.).

ꢁ

Fixed- 500KHz or Adjustable Frequency

Synchronous PWM Operation.

The device features an internal synchronous

rectifier for high conversion efficiency. Excellent

noise characteristics and fixed-frequency

operation provide easy post-filtering. The

AIC1555 is ideally suited for Li-ion battery

applications. It is also suitable for +3V or +5V

fixed input applications. The device can operate

in either one of the following four modes.

Synchronizable external Switching Frequency

up to 1MHz.

ꢁ

Constant Over-current-protection mode.

Accurate Reference: 0.75V ( 2.5%).

100% Duty Cycle in Dropout.

ꢁ

Low Profile 8-Pin MSOP Package.

APPLICATIONS

(1) Forced PWM mode operates at a fixed

PDAs.

ꢁ

frequency regardless of the load.

Digital Still Cameras.

Handy-Terminals.

Cellular Phones.

(2) Synchronizable PWM mode allows the

synchronization by using an external

switching frequency with

harmonics.

minimum

Cordless Phones.

Notebook Chipset Supplies.

(3) PWM/PFM Mode extends battery life by

switching to a PFM pulse-skipping mode

under light loads.

Battery-Operated Devices (4 NiMH/ NiCd or 1

Li-ion Cells).

(4) Shutdown mode sets device to standby,

reducing supply current to 0.1µA or under.

The AIC1555 can deliver over 700mA output

current. The output voltage can be adjusted

from 0.75V to VIN ranging from +2.5V to +6.5V.

Other features of the AIC1555 include low

quiescent current, low dropout voltage, and a

0.75V reference of 2.5% accuracy. It is

available in

package.
