1 / 55 page  TPS65023, TPS65023B www.ti.com SLVS670J – JUNE 2006 – REVISED SEPTEMBER 2011 POWER MANAGEMENT IC FOR LI-ION POWERED SYSTEMS Check for Samples: TPS65023, TPS65023B 1 FEATURES DESCRIPTION 23 • 1.7 A, 90% Efficient Step-Down Converter for The TPS65023, TPS65023B is an integrated Power Processor Core (VDCDC1) Management IC for applications powered by one • 1.2 A, Up to 95% Efficient Step-Down Li-Ion or Li-Polymer cell, and which require multiple Converter for System Voltage (VDCDC2) power rails. The TPS65023, TPS65023B provides • 1.0 A, 92% Efficient Step-Down Converter for three highly efficient, step-down converters targeted at providing the core voltage, peripheral, I/O and Memory Voltage (VDCDC3) memory rails in a processor based system. The core • 30 mA LDO/Switch for Real Time Clock (VRTC) converter allows for on-the-fly voltage changes via • 2 × 200 mA General-Purpose LDO serial interface, allowing the system to implement • Dynamic Voltage Management for Processor dynamic power savings. All three step-down converters enter a low-power mode at light load for Core maximum efficiency across the widest possible range • Preselectable LDO Voltage Using Two Digital of load currents. The TPS65023, TPS65023B also Input Pins integrates two general-purpose 200 mA LDO voltage • Externally Adjustable Reset Delay Time regulators, which are enabled with an external input pin. Each LDO operates with an input voltage range • Battery Backup Functionality between 1.5 V and 6.5 V, allowing them to be • Separate Enable Pins for Inductive Converters supplied from one of the step-down converters or • I2C ™ Compatible Serial Interface directly from the battery. The default output voltage of the LDOs can be digitally set to 4 different voltage • I2C ™ Setup and Hold Timing: combinations using the DEFLDO1 and DEFLDO2 – TPS65023: 300ns pins. The serial interface can be used for dynamic – TPS65023B: 100ns voltage scaling, masking interrupts, or for dis/enabling • 85- μA Quiescent Current and setting the LDO output voltages. The interface is compatible with the Fast/Standard mode I2C • Low Ripple PFM Mode specification, allowing transfers at up to 400 kHz. The • Thermal Shutdown Protection TPS65023, TPS65023B is available in a 40-pin (RSB) • 40 Pin, 5 mm × 5 mm QFN Package QFN package, and operates over a free-air temperature of –40°C to 85°C. APPLICATIONS • Digital Media Players • Internet Audio Player • Digital Still Camera • Smart Phones • Supply DaVinci ™ DSP Family Solutions 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 DaVinci, PowerPAD are trademarks of Texas Instruments. 3 I2C is a trademark of NXP Semiconductors.
