16A Highly Integrated SupIRBuck  
IR3895  
SingleInput Voltage, Synchronous Buck Regulator  
FEATURES  
DESCRIPTION  
The IR3895 SupIRBuckTM is an easytouse, fully  
Single 5V to 21V application  
integrated and highly efficient DC/DC regulator.  
The onboard PWM controller and MOSFETs make  
IR3895 a spaceefficient solution, providing accurate  
power delivery.  
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  
IR3895 is a versatile regulator which offers  
programmable of switching frequency and the fixed  
internal current limit while operates in wide input and  
output voltage range.  
Enable input with Voltage Monitoring Capability  
Thermally Compensated Current Limit with robust  
The switching frequency is programmable from 300kHz  
to 1.5MHz for an optimum solution.  
hiccup mode over current protection  
Smart internal LDO to improve light load and full load  
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.
