UCD3138OL40EVM-032

EVALUATION BOARD, POWER MANAGEMENT.

The 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 40pin 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.
