4.5V-40V Vin, 600mA Synonous Step-down DCDC Converter

Overview

TopologyBuck Converter
Input voltage4.5-40 V
Output 112 V / 0.6 A
IC revision1.0

Description

The EV2400-B-02A Evaluation Board is designed to demonstrate the capabilities of SCT2400, high efficiency fully integrated synchronous step-down DCDC converter supporting up to 0.6A continuous output current from an input source from 4.5V to 40V.The SCT2400 features fixed 2MHz switching frequency,which minimizes the external off chip passive components size and reduces the output ripple to be lower than 0.1% of output when the output is 12V. With a minimum 100ns on-time of high-side MOSFET, the SCT2400 allows power conversion from high input voltage to low output voltage.The SCT2400 offers cycle-by-cycle current limit,thermal shutdown protection and input voltage under voltage protection. The device is available in a 6-pin small profile TSOT23-6 package.This user's guide describes the characteristics,operation and the use of the EV2400-B-02A Evaluation Module including EVM specifications,recommended test setup, test result, schematic diagram, bill of materials, and the board layout.
