Setup and Test Results

2 Setup and Test Results

This section explains the input, output, and jumper connections of the TPS65162EVM-278. It also

describes how to set up test equipment for evaluating the EVM and provides test results.

2.1 Connections and Jumpers

The DEFAULT jumper settings are required for the EVM to operate within the specifications of Table 1.

Table 2. Default Jumper Settings

Jumper Default Setting

J6 – Enable 1 (OFF) GND

J7 – Enable 2 (OFF) GND

J8 – Freq Control (750 khz) Vin

J9 – Enable Gate Voltage Shaping (ON) Vin

J10 – Control Gate Voltage

(ON) Vin

Shaping

J1-VIN/GND: Input power supply and ground connection, Vin range 8 V to 14 V

J2-Vs/GND: Output connection for the main boost converter and ground return connection

J3-VLOGIC/GND: Output voltage for 3.3-V buck converter and ground return connection

J4-VGH/GND: Output connection for the internal high-voltage switch and ground return connection

J5-VGL/GND: Output voltage for negative charge pump and ground return connection

J6–Enable 1: Enable for VLOGIC converter, GND = OFF, VIN = ON

J7–Enable 2: Enable for positive charge pump, GND = OFF, VIN=ON

J8–Freq Control: Frequency Selection, GND = 750 kHz, Vin = 500 kHz

J9–Enable Gate Gate Voltage Shaping, GND = OFF, VIN = ON

Voltage Shaping:

J10–Control Gate Control Voltage Shaping, GND = OFF, VIN = ON

Voltage Shaping:

J11-OPAMP 1: Opamp 1 input, output, gnd, and VS connection

J12-OPAMP 2: Opamp 2 input, output, gnd, and VS connection

J13-NEG1: Opamp 1 connection negative input and output

J14-NEG2: Opamp 2 connection negative input and output

J15- VGL reference voltage and ground return

GND/REFERENCE

J16-VS test point: Test point for VS

J17-VGH test point: Test point for VGH

J18-VGL test point: Test point for VGL

J19-VLOGIC test Test point for VLOGIC

point:

2.2 Recommended Test Setup

Before turning on the power supply, ensure that jumpers J6--J10 are in their default positions.

Connect a power supply rated at 3 A or more to provide 8 V to 14 V to J1. Do not exceed 14 V on J1. In

order to avoid voltage drop through the input power supply line, connect heavy-gauge, twisted-pair wire to

J1. The output voltages can be monitored by voltmeters and/or an oscilloscope with standard

high-impedance voltage probes.
