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
