1 Introduction

The Texas Instruments TPS63030EVM-658 evaluation module contains a TPS63030 buck-boost

converter integrated circuit (IC), supporting components, and one white light-emitting diode (WLED). The

purpose of this EVM is to facilitate evaluation of the TPS63030 in a typical WLED application.

Table 1 provides a summary of the TPS63030EVM-658 performance specifications. All specifications are

given for an ambient temperature of 25°C.

1.2 Modifications

To aid user customization of the EVM, the board was designed with devices having 0603 or larger

footprints. Actual implementations may occupy less space. Resistor R6 may be removed to measure

current through the LED.

2 TPS63030EVM-658 Setup

2.1 Input/Output Connections

The connection points and jumper positions are described in the following paragraphs.

2.1.1 J1 – V

This header is the positive connection for the input power supply. Twist the leads to the input supply and

keep them as short as possible. The input voltage must remain within the limits specified in Table 1.

2.1.2 J2 – Sense + and -

This header is low current sense lines that monitor Vin at the input capacitor.

2.1.3 J3 – GND

This header is the return connection to the input power supply.

2.1.4 J4 – LED Out

This header is voltage out of the converter to the LED

2.1.5 JP1 – Enable

This jumper connects the enable pin of the TPS63030 to either ON (enabling the TPS63030) or OFF

(disabling the TPS63030). The jumper must be installed in one position only. Do not leave JP1 open.

WARNING

This EVM WLED shines brightly. Protective eyewear and use of the

diffuser cover is recommended.
