Analog Devices ADPL76030 | Demoboard EVAL-ADPL76030

Description

The ADPL76030 evaluation kit (EV kit) is a fully assembled and tested circuit board that demonstrates the features of the ADPL76030, a synchronous 4-switch buck-boost DC/DC controller in a 28-lead 4 mm x 5 mm QFN package. The proprietary peak-buck, peak-boost current-mode control scheme allows adjustable and synchronizable 600 kHz to 1.4 MHz fixed frequency operation, or internal 25% triangle spread-spectrum frequency modulation for low EMI. The board accepts a continuous 4 V to 25 V input voltage with transient voltage up to 55 V. Various test points are available for monitoring (PGOOD and ISMON) and control (EN/UVLO, CTRL, and SYNC). Optional EMI input, output, and gate resistor component placeholders are included to support the option of adding, if required.
