1.4 Device Information

The EVM is for TPSM82830x device family. The TPSM82830x is a family of pin-to-pin compatible 1-A, 2-A and 3-A high efficiency and easy to use synchronous step-down DC/DC power modules with integrated inductors. Based on the DCS-Control topology, the device provides a fast transient response with small output capacitance. The internal reference allows to regulate the output voltage down to 0.5 V with a high feedback voltage accuracy of 1% over the junction temperature range of –40°C to 125°C. The nominal switching frequency is 2 MHz with a controlled variation over the input voltage range. The MODE pin allows for an easy selection for the mode of operation. If PSM is selected, the converter operates in DCM at light load conditions with a reduced switching frequency to maintain a high efficiency, and seamlessly transition to CCM as the load current increases to medium or heavy ranges. If forced-PWM is selected, the converter maintains a CCM operation regardless of the load current to maintain a minimum output voltage ripple. The family offers excellent EMI performance and comes in a 3-mm × 3-mm × 2-mm QFN package.
