1 / 40 page LM10500 www.ti.com SNVS630G – SEPTEMBER 2009 – REVISED MARCH 2013 LM10500 5A Step-Down Energy Management Unit (EMU) With PowerWise™ Adaptive Voltage Scaling (AVS) Check for Samples: LM10500 1 FEATURES DESCRIPTION The LM10500 is a 5A Energy Management Unit 23 • Closed-Loop Adaptive Voltage Scaling (AVS) (EMU) that actively reduces system-level power • PWI 1.0 / PWI 2.0 Compatible consumption by utilizing a continuous, real-time, • Resistor-Programmable switching frequency closed-loop Adaptive Voltage Scaling (AVS) scheme. The LM10500 operates cooperatively with • Frequency Synchronization PowerWise™ AVS compatible ASICs, SoCs, and • Precision Enable processors to optimize supply voltages adaptively • Internal Soft-Start to Reduce In-Rush Current over process and temperature variations. The device is controlled via PowerWise Interface (PWI) 1.0 or • Power Good (PWROK) PWI 2.0 high-speed serial interface. • Under-Voltage Lock Out (UVLO) A typical power saving of 40% can be achieved when • Over-Voltage Protection (OVP) LM10500 is used with AVS compatible ASICs, SoCs, • Cycle-by-cycle current limiting (OCP) and processors. • Thermal Shutdown KEY SPECIFICATIONS • 3.0 V to 18.0 V Input Voltage Range • 1.5% Feedback Voltage Accuracy • 0.6 Vto 1.0 V AVS Feedback Voltage Range • 0.8 Vto 5.0 V Startup VOUT Range (Using Resistor-Divider) • AVS Typical Power Saving 40% Over Fixed Voltage • 300 kHz to 1.5 MHz Switching Frequency Range • WQFN-28 Package (5 mm x 5 mm x 0.8 mm, 0.5 mm pitch) APPLICATIONS • Point-of-Load Regulation • Servers and Networking Cards • Storage Devices • Set-Top-Box Processors • Medical and Industrial Processors 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 PowerWise is a trademark of Texas Instruments. 3 All other trademarks are the property of their respective owners.
