Analog Devices Inc. EVAL-ADPL76030EBZ Evaluation Board
Analog Devices Inc. EVAL-ADPL76030EBZ Evaluation Board 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 4mm x 5mm QFN package. A proprietary peak-buck/-boost current-mode control scheme allows adjustable and synchronizable 600kHz to 1.4MHz fixed frequency operation or internal 25% triangle spread-spectrum frequency modulation for low EMI. The board accepts a continuous 4V to 25V input voltage with transient voltage up to 55V. 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.
