Overview
| Topology | Buck Converter |
| Input voltage | 4-28 V |
| Output 1 | 5 V / 6 A |
| IC revision | 1.0 |
Description
The EV2361-B-02A Evaluation Board is designed to demonstrate the capabilities of SCT2361, high efficiency fully integrated synchronous step-down DCDC converter supporting up to 6A continuous output current from an input source from 4V to 28V.The SCT2361 integrated 3.3V output LDO has path management between Vin and DC-DC converter output to achieve the lower power loss and better thermal performance. The device has the MODE pin to select Pulse Frequency Modulation (PFM) operation mode to achieve the light load power save,or Ultrasonic Mode (USM) to keep the switching frequency above audible frequency areas during light-load or no-load conditions.SCT2361 fully integrates high-side and low-side power MOSFETs with 36mΩ/18mΩ on-resistance to minimize the conduction loss.This user's guide describes the characteristics,operation and the use of the EV2361-B-02A Evaluation Module including EVM specifications,recommended test setup, test result, schematic diagram, bill of materials, and the board layout.
