LTC3374

8-Channel Parallelable

1A Buck DC/DCs

FEATURES

DESCRIPTION

The LTC^®3374 is a high efficiency multioutput power sup-

ply IC. The DC/DCs consist of eight synchronous buck

converters (1A each) all powered from independent 2.25V

to 5.5V input supplies.

8-Channel Independent Step-Down DC/DCs

Master-Slave Configurable for Up to 4A per Output

Rail with a Single Inductor

Independent V Supplies for Each DC/DC

(2.25V to 5.5V)

The DC/DCs may be used independently or in parallel to

achievehighercurrentsofupto4Aperoutputwithashared

inductor. The common buck switching frequency may be

programmed with an external resistor, synchronized to an

external oscillator, or set to a default internal 2MHz clock.

The operating mode for all DC/DCs may be programmed

via the MODE pin.

All DC/DCs Have 0.8V – V Output Range

Precision Enable Pin Thresholds for Autonomous

Sequencing

1MHz to 3MHz Programmable/Synchronizable

Oscillator Frequency (2MHz Default)

Die Temperature Monitor Output

Thermally Enhanced 38-Lead QFN (5mm × 7mm)

and TSSOP Packages

To reduce input noise the buck converters are phased in

90° steps. Precision enable pin thresholds provide reli-

able power-up sequencing. The LTC3374 is available in a

compact 38-lead 5mm × 7mm QFN package as well as a

38-lead TSSOP package.
