Description
Device Description:
The TPS65910 device is an integrated power-management IC available in 48-QFN package and is
dedicated to applications powered by one Li-Ion or Li-Ion polymer battery cell, 3-series Ni-MH cells, or a 5
V input, and which requires multiple power rails. The device provides three step-down converters, one
step-up converter, and eight low dropout voltage regulators (LDOs) and is designed to support the specific
power requirements of OMAP™ processors.

power requirements of OMAP™ processors.
Two of the step-down converters provide power for dual processor cores and are controllable by a
dedicated class-3 SmartReflex™ interface for optimum power savings. The third converter provides power
for the I/Os and memory in the system. The device includes eight general-purpose LDOs providing a wide
range of voltages and current capabilities. These LDOs can be controlled by the inter-integrated circuit

EPROM Power-Up Sequence Description:
This user guide is common for all TPS65910x parts. The only difference in these parts is the EEPROM
sequence for power-up. Each part has a unique EEPROM sequence to satisfy the attached application
processor. For details of the EEPROM sequence please refer to the corresponding user guide in the
“Application Notes” section on the TPS65910x folder page.
