20V, 5A/6A Fully Integrated Synchronous Buck Converters

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.
