ZHCSI09S June 2010 – August 2018 TPS65911
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.
