The UCD9224EVM-464 is designed as two independent single-phase POL voltage rails using the UCD9224 Digital Controller and the PTD08D210W PowerTrain module. The voltage rails are pre-configured to operate from an input voltage source of 12V +/- 10% and produce output voltages of 2.5V (Vout1) and 1.2V (Vout2), each of which can source up to 10A. The UCD7242 Dual Synchronous-Buck Power Driver, the foundation of the PTD08D210W, combines and optimizes the MOSFET driver and the high and low side power MOSFETs for both voltage rails along with fault and monitoring circuitry that integrates with the digital controller.
If a designer wants to monitor or modify the UCD9224EVM-464 using a computer, a separate USB Interface Adapter EVM is recommended. The USB-TO-GPIO Adapter serves as an interface adapter or a bridge between a host PC (IBM compatible) and one or multiple slave devices via a standard type-A to mini-B USB cable. The USB-TO-GPIO Adapter is listed below in the related tools section. The adapter is available for purchase separately from the UCD9224EVM-464 Evaluation Module.
