Applications, Implementation, and Layout

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

7.1

Application Information

The TPS65911 device is an integrated power management IC (PMIC) available in a 98-pin 0.65-mm pitch

BGA MicroStar Junior package. The device is designed for applications powered by one Li-Ion or Li-Ion

polymer battery cell, 3-series Ni-MH cells, or a 5-V input supply. The device has three step-down

converters, one step-down controller with external FETs to support high current rails, eight LDO

regulators, nine GPIOs, and EERPOM-programmable power sequencing to support a variety of

processors and system sequencing requirements.

The following sections include a typical application diagram, description of the recommended external

components, and PCB layout guidelines. The TPS65911x Schematic Checklist is available and provides

recommended connections for each pin.

7.2

Typical Application

The default voltages in Figure 7-1 reflect the TPS65911A configuration. Other TPS65911 device options

may have different default voltages.
