Page 7: Introduction
Chapter 1 Introduction The Texas Instruments TPS61100 to TPS61107 evaluation modules (EVM) for high-efficiency boost converters help designers to evaluate the different operating modes and the performance of the device. Refer to Table 1–1 for the various EVMs available in this family. -
Page 9: Setup Of The Evms
Chapter 2 Setup of the EVMs It is important to establish all connections to the EVM before the power supply for the EVM is turned on. Connect a power supply (0.9 V to V , depending on the output voltage of the EVM) to the INPUT header Connect a voltmeter to the OUTPUT header Verify that all jumper s are set to their desired value (EN, ENPB, SKIPEN,... -

Evaluation With the TPS6110x EVM 2.1 Evaluation With the TPS6110x EVM This chapter details the evaluation process and features of the EVM. For this evaluation, a load is connected to the output terminal in order to adjust the load current between 0 mA and 250 mA. For accurate output voltage and input voltage measurements, it is important to measure the voltage on the input and output voltage terminals with Kelvin contacts or with a voltmeter connected directly to the input voltage or output... -
Page 11: Lbi/Lbo Comparator
Evaluation With the TPS6110x EVM 2.1.5 LBI/LBO Comparator The LBO1 and LBO2 terminals are open drain outputs and have pullup resistors, R7 and R8, connected to the output. The signal on these pins can go low as soon as the input voltage at LBI falls below the threshold of 500 mV. Refer to the more detailed description and the truth table in the datasheet. -
