●Introduction
●The TPS65951 device is a power-management IC for mobile cellular handsets powered by a Li-ion, Li-ion polymer, or cobalt-nickel-manganese cell battery. It can be connected to an application processor and/or a modem. This optimized power-management IC is designed to support the specific power requirements of the OMAP processor devices. The TPS65951 contains several buck converters, low dropout (LDO) regulators, battery charger interface, and a host of other features and functions. The audio portion of the TPS65951 is an entire audio module with audio codecs, digital filters, input preamplifiers/amplifiers, and class D output amplifiers.
