12A Highly Integrated SupIRBuck  
IR3894  
SingleInput Voltage, Synchronous Buck Regulator  
FEATURES  
DESCRIPTION  
integrated and highly efficient DC/DC regulator.  
The onboard PWM controller and MOSFETs make  
IR3894 a spaceefficient solution, providing accurate  
power delivery.  
The IR3894 SupIRBuckTM is an easytouse, fully  
Single 5V to 21V application  
Wide Input Voltage Range from 1.0V to 21V with  
external Vcc  
Output Voltage Range: 0.5V to 0.86* Vin  
Enhanced Line/Load Regulation with FeedForward  
Programmable Switching Frequency up to 1.5MHz  
Internal Digital SoftStart/SoftStop  
IR3894 is a versatile regulator which offers  
programmable switching frequency and the fixed  
internal current limit  
Enable input with Voltage Monitoring Capability  
The switching frequency is programmable from 300 kHz  
to 1.5MHz for an optimum solution.  
Thermally Compensated Current Limit with robust  
hiccup mode over current protection  
It also features important protection functions, such as  
PreBias startup, thermally compensated current limit  
over voltage protection and thermal shutdown to give  
required system level security in the event of fault  
conditions.  
Smart internal LDO to improve light load and full load  
efficiency  
External Synchronization with Smooth Clocking  
Enhanced PreBias StartUp  
Precision Reference Voltage (0.5V+/0.5%) with  
margining capability  
APPLICATIONS  
Netcom Applications  
Vp for Tracking Applications ((Source/Sink Capability  
+/12A)  
Embedded Telecom Systems  
Server Applications  
Integrated MOSFET drivers and Bootstrap Diode  
Thermal Shut Down  
Storage Applications  
Programmable Power Good Output with tracking  
capability  
Distributed Point of Load Power Architectures  
Monotonic StartUp  
Operating temp: 40oC < Tj < 125oC  
Small Size: 5mm x 6mm PQFN  
Leadfree, Halogenfree and RoHS Compliant
