Introduction

1 Introduction
The TPS62866 is a synchronous, step-down converter in a 1.05- x 1.78- x 0.5-mm wafer chip-scale package
(WCSP).
1.1 Performance Specification
Table 1-1 provides a summary of the TPS62866EVM-051 performance specifications.

1.2 Modifications
The EVM can support variance of the whole IC family. Additional input and output capacitors can be added.

2 Setup

This section describes how to properly use the TPS62866EVM-051.
2.1 Input/Output Connector Descriptions
J1, Pin 1 and 2 – VIN
J1, Pin 3 and 4 – S+/S- Input voltage sense connections. Measure the input voltage at this point.
J1, Pin 5 and 6 – GND Input return connection from the input supply for the EVM
J2, Pin 1 and 2 – VOUT Output voltage connection
J2, Pin 3 and 4 – S+/S- Output voltage sense connections. Measure the output voltage at this point.
J2, Pin 5 and 6 – GND Output return connection
J3, Pin 5 – VBUS
J3, Pin 6 – GND
J3, Pin 9 – SCL
J3, Pin 10 – SDA
JP1 – VID/PG
JP2 – EN
2.2 Setup
To operate the EVM, set jumpers JP1 and JP2 to the desired position per
to J1 and connect the load to J2.

TEST CONDITIONS
Positive input connection from the input supply for the EVM
The VBUS pin of this header is used to bias the SCL and SDA nodes of I²C interface
via a resistor.
The GND pin of this header is used to connect the grounds of the IC and the I²C
interface.
The pin of this header should be connected to the SCL of the I²C interface.
The pin of this header should be connected to the SDA of the I²C interface.
VID/ PG pin jumper. Always place the jumper across VID/ PG and LOW pins before
start-up. This sets the output voltage and device address. After startup, VOUT reflects
the value set on V Register 1 if the jumper is placed across VID/ PG and LOW
OUT
pins. VOUT follows the value set on V
VID/ PG and HIGH pins.
EN pin input jumper. Place the jumper across ON and EN to turn on the IC. Place the
jumper across OFF and EN to turn off the IC.
