When the PMIC is not fully loaded, buck1 can be loaded to 3.5A and buck 2 and 3 to 2.5A. As there are many possible options to set the converters, table 1 presents the performance specification summary for the EVM. Table 1-1. Input Voltage and Output Current Summary Evaluation Module Test Conditions Output Current Range TPS652510EVM Vin = 4.5 V to 15 V Fsw = 500 KHz Buck1, 1.2 V, 3A Buck2, 1.8 V, 3A Buck3, 3.3 V, 3A (25°C ambient) This evaluation module is designed to provide access to the features of the TPS652510. Some modifications can be made to this module to test performance at different input and output voltages, current and frequency operation. Please contact TI Field Applications Group for advice on these matters. 2 TPS652510 Buck Converter Evaluation Module User's Guide Copyright © 2021 Texas Instruments Incorporated SLVU570A – SEPTEMBER 2011 – REVISED MAY 2021 Submit Document Feedback www.ti.com Power-up Procedure 2 Power-up Procedure 1. Define which converters are to be enabled or disabled by connecting jumpers to JP3, JP11 and JP20 accordingly, or to wiring external drive signals to the ENx headers. 2. If PGOOD signal is required connect JP27 or wire the PGOOD pin to a pull-up supply 3. Connect loads to the output connectors. 4. Apply a DC voltage to header J3. Polarity is marked on the silk-screen. 5. Converters will start according to the setting on JP3, JP11 and JP20. Check the outputs SLVU570A – SEPTEMBER 2011 – REVISED MAY 2021 Submit Document Feedback TPS652510 Buck Converter Evaluation Module User's Guide Copyright © 2021 Texas Instruments Incorporated 3 TPS652510EVM Schematic www.ti.com 3 TPS652510EVM Schematic The resistor and capacitor values have been chosen according to the guidelines presented on the TPS652510 spec that will be available at http://focus.ti.com/docs/prod/folders/print/TPS652510.html Note that for the purpose of gains-phase measurements R14, R17 and R37 (zero ohm on the EVM) need to be replaced by suitable low value resistors as per the network analyzer setup required. Test points connections are provided on either end of the resistors to allow for easy measurement. 4 TPS652510 Buck Converter Evaluation Module User's Guide Copyright © 2021 Texas Instruments Incorporated SLVU570A – SEPTEMBER 2011 – REVISED MAY 2021 Submit Document Feedback TPS652510EVM Schematic www.ti.com Figure 3-1.
