Beschreibung
The EV2650-B-02A Evaluation Board is designed todemonstrate the capabilities of SCT2650, high efficiency non-synchronous step-down DCDC converter supporting up to 5A continuous output current from an input source from 4.5V to 60V.The SCT2650 features programmable switching frequency from 100 kHz to 1.2 MHz with an external resistor, which provides the flexibility to optimize either efficiency or external component size. The converter supports external clock synchronization with a frequency band from 100kHz to 1.2MHz. The device offers fixed 2ms soft start to prevent inrush current during the startup of output voltage ramping.The SCT2650 features external loop compensation to provide the flexibility to optimize either loop stability or loop response.This user's guide describes the characteristics, operation and the use of the EV2650-B-02A Evaluation Module including EVM specifications, recommended test setup, test result, schematic diagram, bill of materials, and the board layout.
