Introduction 1 www.ti.com Introduction The TPS6507x are a series of single-chip power management ICs for portable applications consisting of a battery charger with Power Path management for a single lithium-ion (Li-Ion) or lithium-polymer (Li-Polymer) cell. The charger can be supplied either by a USB port on the device USB pin or by a dc voltage from a wall adapter connected to the device AC pin. Three highly-efficient, 2.

Introduction www.ti.com 1.3 Requirements In order to operate this EVM properly, the related software and hardware must be connected and properly configured. All components and connectors are installed on the EVM as shipped, except for the host computer and the dc power supply. The most current version of the software must be downloaded from the TI website at www.ti.com. 1.3.

Connector and Test Point Descriptions www.ti.com 4 Connector and Test Point Descriptions 4.1 Input / Output Connector Descriptions 4.1.1 J1: VINLDO1, 2, GND J1 pin 1 is the input supply for LDO1 and LDO2. In the default configuration, VINLDO1,2 is connected to SYS with R1. To connect VINLDO1,2 to any other voltage source, remove R1 and connect the VINLDO1,2 supply between J1 pin 1 (positive connection) and J1 pin 2 (GND connection). 4.1.
PAGE 9
Connector and Test Point Descriptions www.ti.com 4.1.7 J7: VLDO1, GND J7 pins 1 and 2 are connected to the positive output of linear regulator LDO1. J7 pins 2 and 4 are the GND connection for LDO1. A load can be connected between J7 pins 1 and 2 (VLDO1) and J13 pins 3 and 4 (GND). LDO1 is able to supply a load current up to 200 mA. 4.1.8 J8: VLDO2, GND J8 pins 1 and 2 are connected to the positive output of linear regulator LDO2. J8 pins 2 and 4 are the GND connection for LDO2.

Connector and Test Point Descriptions 4.1.15 www.ti.com J15: PB_IN, PB_OUT, POWER_ON, PGOOD, RESET/EN_EXTLDO, INT J15, pin 1: PB_IN J15 pin 1 is connected to PB_IN. Pulling PB_IN low starts up all dc-dc converters and LDOs according to the internal power-up sequence. Refer to Table 9 in the data sheet (SLVS950) for information on the internal power-up sequence. Note that if PB_IN is released high, all dc-dc converters and LDOs shut down if the POWER_ON input is low.
PAGE 11
Connector and Test Point Descriptions www.ti.com 4.2 4.2.1 Enable Jumpers / Switches S1: PB_IN S1 is connected to PB_IN. Pressing the switch S1 pulls the PB_IN pin of the TPS6507x low, starting up all dc-dc converters and LDOs according to the device internal sequence. Note that if S1 is released, all dc-dc converters and LDOs shut down if the POWER_ON input is low. If POWER_ON is pulled high before PB_IN is released high again, the dc-dc converters and LDOs remain on.

Setup 5 www.ti.com Setup CAUTION Many of the components on the TPS6507xEVM-430 are susceptible to damage by electrostatic discharge (ESD). Customers are advised to observe proper ESD handling precautions when unpacking and handling the EVM, including the use of a grounded wrist strap, bootstraps, or mats at an approved ESD workstation. An electrostatic smock and safety glasses should also be worn. 5.

EVM Assembly Drawings and Layout www.ti.com 6 EVM Assembly Drawings and Layout Figure 4 through Figure 9 show the design of the TPS65070EVM-430 printed circuit boards. This EVM has been designed using a four-layer, 1-ounce copper-clad PCB with all components in an active area on the top side of the board. NOTE: Board layouts are not to scale. These figures are intended to show how the board is laid out; they are not intended to be used for manufacturing TPS65070EVM-430 PCBs. Figure 4.
