TPS65951 Integrated Power Management IC (PMIC) Audio Codec Silicon |

TPS65951 (NRND)

Integrated Power Management IC (PMIC) Audio Codec Silicon



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. The device 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, a 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 and amplifiers, and class-D output amplifiers.
