General Description

The ADPL12008/ADPL12010 ICs are highly integrated

synchronous buck converters with internal high-side and

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

8A/10A with an input voltage from 3V to 20V. The

voltage quality can be monitored by the PGOOD signal.

The ICs can operate in dropout mode by running at a

very high duty cycle, making them ideal for factory

automation applications.

The ADPL12008/ADPL12010 ICs offer programmable

output-voltage options. High switching frequency at

1.5MHz and 400kHz options allow for small external

components and reduced output ripple. SYNC input

programmability enables three modes for optimized

performance: Forced–Pulse-width modulation (PWM)

mode, skip mode with ultra-low quiescent current, and

synchronization to an external clock.

The ADPL12008/ADPL12010 ICs also feature dual-

phase capability, which allows up to 20A designs. Two

ICs can be configured as a controller and target with

dynamic current sharing and 180º out-of-phase

operation.

The ADPL12008/ADPL12010 ICs are available in a

small, 3.5mm x 3.75mm, 17-pin flip-chip quad flat

no-lead (FC2QFN) package. They are pin-to-pin

compatible with the ADPL12005/ADPL12006 (5A to 6A)

family of products.
