Texas Instruments UCD3138OL40EVM-032

UCD3138OL40EVM-032 EVM offers an easy to use test platform for stand-alone evaluation of UCD3138 digital controller optimized for isolated power applications. Featuring a 40-pin socket and comprehensive set of test points, the EVM allows hardware and firmware engineers to manipulate signals on the different pins of the device individually and study open loop operation. The EVM also offers the flexibility to realize simple closed loop control configurations (eg. using RC circuits to filter PWM output signals and regulate a DC voltage in closed loop control). Hardware ports available to communicate with the device include PMBus, UART and JTAG. The EVM accepts up to 5V DC input and an on-board 3.3V LDO can be used to bias the device. Alternately, using jumpers, the device can be biased using the PMBus communication pins. NOTE: In order to download firmware and program the UCD3138 device in UCD3138OL40EVM-032, a separate EVM from Texas Instruments known as the USB-TO-GPIO Adapter is required. The USB-TO-GPIO Adapter is NOT supplied with UCD3138OL40EVM-032 and must be purchased separately. The USB-TO-GPIO Adapter serves as a communication interface adaptor or a bridge between a host PC and the UCD3138 via a standard type-A to mini-B USB cable. The USB-TO-GPIO Adapter is listed below in the related products section.
