Texas Instruments Simple Switcher Power Module for LMZ14203

The SIMPLE SWITCHER® power module evaluation board is optimized for peak performance and increased flexibility. By incorporating additional ceramic and an aluminum filter capacitor, the power module EVAL board demonstrates the low output ripple, fast transient response, and low conducted and radiated EMI performance of the device. Adjusting the output voltage, optimizing the control loop circuitry, and fine-tuning the filter capacitance is easy, with convenient size and placement of the passive components on the board. Finally, the excellent thermal performance of the power modules is enhanced using a 4-layer PCB.
