Chapter 1 Introduction The Texas Instruments TPS62020 evaluation module (EVM) for low-power, high-efficiency, step-down converters helps designers evaluate this device. The EVM enables evaluation of different device modes and device performance. The TPS62020EVM is set to 1.5 V. The TPS62020EVM can be easily set up to provide any output voltage between 0.7 V and 6 V (or Vin) by adjusting the external resistor divider. See the TPS62020 data sheet (SLVS076) for the output voltage calculation.
Introduction 1.1 EVM Ordering Information Table 1-1 provides EVM ordering information. Table 1-1. EVM Ordering Information EVM Number TPS62020EVM-019 Description Adjustable output voltage version set to 1.
Chapter 2 Evaluation With the TPS62020EVM This chapter details the EVM evaluation process and features. A load is connected to the output pins Vout and GND, which allows the load current to be adjusted between 0 A and 0.6 A. For accurate output voltage and input voltage measurements, it is important to measure the voltage on the input and output voltage terminals with a voltmeter connected directly to the input voltage or output voltage terminals.
Evaluation With the TPS62020EVM 2.1 Enable (EN) Jumper This jumper is used to enable the device. Connecting the EN pin to ENABLE enables the part. Connecting the EN pin to DISABLE disables the device. 2.2 Mode Selection Jumper This jumper is used to choose between PWM and PFM/PWM modes of operation. Setting the jumper across FIXED FREQ forces the device into the low-noise fixed frequency pulse width modulation (PWM) mode.
