Single-Input Voltage, Synchronous Buck Regulator
35A Highly Integrated SupIRBuck®
FEATURES
DESCRIPTION
The IR3846 SupIRBuck® is an easy-to-use, fully integrated and highly efficient DC/DC regulator. The onboard PWM controller and MOSFETs make IR3846 a space-efficient solution, providing accurate power delivery for low output voltage and high current applications.
IR3846 is a versatile regulator which offers programmability of switching frequency and current limit while operating in wide input and output voltage range.
The switching frequency is programmable from 300 kHz to 1.5MHz for an optimum solution.
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.
APPLICATIONS
ABSOLUTE MAXIMUM RATINGS
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications are not implied.
