Texas Instruments SN6505B | Demoboard TMDSCNCD2800137

Low-noise, 1-A, 420-kHz transformer driver with soft start for isolated power supplies

Overview

TopologyPush-Pull Converter symmetrical isolated
Input voltage5 V
IC revisionB

Description

TMDSCNCD2800137 is a low-cost evaluation and development board for TI C2000™ MCU series of TMS320F280013x devices. It comes with a HSEC180 (180-pin high-speed) edge connector and, as a controlCARD, is ideal for initial evaluation and prototyping. For evaluation of TMDSCNCD2800137, a 180-pin docking station TMDSHSECDOCK is required and can be purchased separately.
