TI’s TPS65050 family of converters efficiently manages power in today’s leading applications processors, such as TI’s OMAPT processors, TMS320C55xT generation of digital signal processors (DSPs) and others. The six-channel devices maximize up to 95 percent efficiency across a wide range of point-of-load currents up to 1 A.
The TPS65050 integrates two 2.25-MHz step-down converters to support the system’s core, peripheral, I/O or memory voltages. Both of the converters, which operate at input voltages from 2.5 V to 6 V, allow the device to operate in a power-save mode at light-load currents, and can be placed in a shutdown mode when power consumption is reduced to less than 1 uA. The TPS65050 also integrates two general-purpose, 400-mA linear dropout (LDO) voltage regulators and two 200-mA LDOs that can be enabled with an external input pin for each LDO. In addition, the LDOs support an input voltage between 1.5 V and 6.5 V, which allows each to be supplied from one of the integrated step-down converters or directly from the battery.
The TPS65050 family of converters is available in volume production from TI and its authorized distributors. The devices come in a 32-pin, 4 mm x 4 mm, leadless QFN package. The TPS65050’s 2.25-MHz frequency also allows a designer to implement a tiny 2.2-uH inductor and ultra-small
capacitors to achieve a small solution size. Suggested retail pricing starts at $2.75 in 1,000-unit quantities. Evaluation modules of the TPS65050, application notes and TI’s comprehensive portfolio of power management ICs are available.
