General Description

The

ADPL12005/ADPL12006

ICs

are

small,

synchronous buck converters with integrated high-side

and low-side switches. The ICs are designed to deliver

up to 6A with wide input voltages ranging from 3V to

20V. Voltage quality can be monitored by observing the

PGOOD signal. The ICs can operate in dropout by

running at a very high duty cycle, making it ideal for

factory automation applications.

The ADPL12005/ADPL12006 ICs offer programmable

output voltage. The frequency is internally fixed at

400kHz and 1.5MHz, allowing for small external

components and reduced output ripple. The ICs

automatically enter skip mode at light loads with ultra-

low quiescent current of 20μA at no load. This family of

products (including the ADPL12008/ADPL12010) offers

a pin-to-pin compatible offering from 5A to 10A in a

single-phase configuration, and up to 20A in a dual-

phase configuration. These devices are also optimized

for dual-phase operation with very high current-sharing

accuracy.

The ADPL12005/ADPL12006 ICs are available in a

small 3.5mm x 3.75mm, 17-pin flip-chip quad flat no-lead

(FC2QFN)

package,

utilizing very

few external

components.
