Highly Integrated 35A Singleinput Voltage,  
iP1837  
Synchronous Buck Regulator  
FEATURES  
DESCRIPTION  
The iP1837 iPOWIRTM is an easytouse, fully integrated  
and highly efficient DC/DC regulator. The onboard PWM  
controller and MOSFETs make iP1837 a spaceefficient  
solution, providing accurate power delivery for low output  
voltage and high current applications.  
Wide input application 1.5V16V  
Single 3.3V or single 5V application  
Output Voltage Range: 0.6V to 0.75*Vin  
0.5% accurate Reference Voltage  
Programmable Switching Frequency up to 1.5MHz  
Programmable SoftStart  
iP1837 is a versatile regulator which offers programmability  
of switching frequency and current limit while operating in  
wide input and output voltage range.  
Enable input with Voltage Monitoring Capability  
Remote Sense Amplifier with True Converter  
Voltage Sensing  
The switching frequency is programmable from 250kHz to  
1.5MHz for an optimum solution.  
Thermally compensated Hiccup Mode  
Over Current Protection  
It also features important protection functions, such as  
PreBias startup, hiccup current limit and thermal  
shutdown to give required system level security in the  
event of fault conditions.  
Overvoltage protection  
PreBias Start up  
Body Braking to improve transient  
Integrated MOSFET drivers and Bootstrap diode  
Operating temp: 40oC<Tj<125oC  
Thermal Shut Down  
APPLICATIONS
