ANALOG DEVICES EVAL-ADPL76030EBZ Evaluation Board, ADPL76030, Synchronous Buck-Boost Controller, Power Management

EVAL-ADPL76030EBZ is an ADPL76030 evaluation kit (EV kit) that is 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. The proprietary peak-buck, peak-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 to support the option of adding, if required. Component placement and board layout as part of the overall design is essential for proper electrical and thermal performance. ADPL76030 provides input or output current monitor and power good flag.
