製品概要
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.
Read the ADP76030 data sheet with this user guide for a proper understanding and operation of the controller and its numerous features. Component placement and board layout as part of the overall design is essential for proper electrical and thermal performance.
The ADPL76030 provides input or output current monitor and power good flag. Fault protection is also provided to detect output short-circuit condition, during which the ADPL76030 retries, latches off, or keeps running.
