1 / 46 page  LP8725 www.ti.com SNVS618G – DECEMBER 2009 – REVISED MAY 2013 LP8725 Power Management Unit for Application or Multimedia Processors and Subsystems Check for Samples: LP8725 1 FEATURES KEY SPECIFICATIONS 2 • Two High-Efficiency Step-Down DC-DC • 190 mV typ. Dropout Voltage on digital LDOs Converters, IOUT = 600 mA, With a 4-MHz @ 300 mA Switching Frequency Using Small 1-µH • 2% typ. Output Voltage Accuracy on digital Inductors, With Options up to 800 mA and analog LDOs • Three Digital LDOs for up to 300-mA Load • 10 μVrms Output Noise on analog LDOs Current Each • ±2% typ. Output Voltage Bucks up to 93% • Two Low-Noise Analog 300-mA LDOs efficiency • Two Low-Input Low-Output Regulators, • 30-bump DSBGA package (0.5 mm pitch) IOUT = 300 mA • I2C-Compatible Interface for Control of Internal DESCRIPTION Registers This device is a multi-function programmable Power Management Unit (PMU), optimized for sub block • Adjustable Startup Sequence Through Serial power solutions. This device integrates two highly Interface or Configuration efficient 600-mA step-down DC-DC converters • Thermal Shutdown Protection configurable up to 800-mA load with Dynamic Voltage Scaling (DVS) via the serial interface, two low-noise APPLICATIONS analog LDOs, three digital LDOs for up to 300 mA load current each, two Low-Input Low-Output (LILO) • Multimedia Processors regulators, and an I2C-compatible serial interface to • Portable Handheld Products allow a host controller access to the internal control registers. The device also features programmable power-on sequencing. LDO regulators provide high PSRR and low noise ideally suited for supplying power to both analog and digital loads. The device can be configured either as a Sub_PMU for modules (for example, camera or multimedia modules) or as a stand-alone PMU that powers the processor itself. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 All trademarks are the property of their respective owners.
