16A Highly Integrated SupIRBuck®  
Single-Input Voltage, Synchronous Buck Regulator  
IR3448  
FEATURES  
DESCRIPTION  
The IR3448 SupIRBuck® is an easy-to-use, fully  
integrated and highly efficient DC/DC regulator. The  
onboard PWM controller and MOSFETs make IR3448  
a space-efficient solution, providing accurate power  
delivery for low output voltage and high current  
applications.  
Single 5V to 21V application  
Wide Input Voltage Range from 1.5V to 21V with  
external Vcc  
Output Voltage Range: 0.6V to 0.86*PVin  
0.5% accurate Reference Voltage  
Enhanced line/load regulation with Feed-Forward  
Programmable Switching Frequency up to 1.5MHz  
Internal Digital Soft-Start  
IR3448 is  
a
versatile regulator which offers  
Enable input with Voltage Monitoring Capability  
programmability of switching frequency and current  
limit while operating in wide input and output voltage  
range.  
Remote Sense Amplifier with True Differential  
Voltage Sensing  
Thermally compensated current limit and Hiccup  
Mode Over Current Protection  
The switching frequency is programmable from 300  
kHz to 1.5MHz for an optimum solution.  
Smart LDO to enhance efficiency  
External synchronization with Smooth Clocking  
Dedicated output voltage sensing for power good  
indication and overvoltage protection which  
remains active even when Enable is low.  
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.  
Enhanced Pre-Bias Start up  
Body Braking to improve transient  
Integrated MOSFET drivers and Bootstrap diode  
Thermal Shut Down  
Post Package trimmed rising edge dead-time  
Programmable Power Good Output  
Small Size 5mm x 6mm PQFN  
APPLICATIONS  
Operating Junction Temp: -40oC<Tj<125oC  
Lead-free, Halogen-free, and RoHS Compliant
