20V, 8A/10A Fully Integrated Buck Converter with 20μA Quiescent Current and Dual-Phase Capability

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.
