Dual output, 6A/Phase, Highly Integrated SupIRBuck®  
IR3892  
Single-Input Voltage, Synchronous Buck Regulator  
FEATURES  
DESCRIPTION  
The IR3892 SupIRBuck® is an easy-to-use, fully  
integrated and highly efficient DC/DC regulator. The  
onboard PWM controller and MOSFETs make IR3892  
a space-efficient solution, providing accurate power  
delivery for low output voltage.  
Single 5V to 21V application  
Wide Input Voltage Range from 1V to 21V with  
external Vcc  
Output Voltage Range: 0.5V to 0.86*PVin  
Dual output, 6A/Phase  
IR3892 is  
a
versatile regulator which offers  
Enhanced Line/Load Regulation with Feed-  
Forward  
programmability of switching frequency and a fixed  
current limit while operating in wide input and output  
voltage range.  
Programmable Switching Frequency up to 1.0MHz  
Internal Digital Soft-Start  
Enable input with Voltage Monitoring Capability  
The switching frequency is programmable from  
300kHz to 1.0MHz for an optimum solution.  
Thermally compensated current limit and Hiccup  
Mode Over Current Protection  
It also features important protection functions, such as  
Over Voltage Protection (OVP), Pre-Bias startup,  
hiccup current limit and thermal shutdown to give  
required system level security in the event of fault  
conditions.  
External synchronization with Smooth Clocking  
Precision Reference Voltage (0.5V +/-1%)  
Seq pin for Sequencing Applications  
Integrated MOSFETs, drivers and Bootstrap diode  
Thermal Shut Down  
APPLICATIONS  
Open Feedback Line Protection  
Sever Applications  
Over Voltage Protection  
Netcom Applications  
Interleaved Phases to reduce Input Capacitors
