Setup

The function of connectors on the TLV61048EVM-042 and their setup is described below:

J1-VPS Positive output of the power supply for the TLV61048EVM.
J2-VOUT Positive connection for the loading.
J3-GND Return connection of the power supply for the TLV61048EVM.
J4-GND Return connection for the loading.
J5-VPS_S power supply sensing for measuring efficiency. VPS_S and GND_S are for positive and negative inputs of the voltage meter.
J6-VOUT_S Output voltage sensing for measuring efficiency. VOUT_S and GND_S are for positive and negative inputs of the voltage meter.
J7-VIN Select the voltage source for the VIN pin of the TLV61048. if short the VIN to VPS, The power supply for the EVM must be higher than 2.6 V. if support the VIN with an additional 3.3-V voltage source, the power supply connected to the VPS can be down to 1.2V.
J8-EN Control the EN pin to enable or disable the TLV61048.
J9-FREQ The device switches with 600-KHz frequency if the FREQ pin is floating, and with 1-MHz if the FREQ is shorted to GND.
