PD97511 IR3837MPbF TM SupIRBuck HIGHLY INTEGRATED 14A SINGLE-INPUT VOLTAGE, SYNCHRONOUS BUCK REGULATOR Features Description Greater than 96% Maximum Efficiency TM The IR3837 SupIRBuck is an easy-to-use, fully Single 16V Application integrated and highly efficient DC/DC regulator. Single 5V Application The onboard PWM controller and MOSFETs Wide Output Voltage Range: 0.6V to 0.9*Vin make IR3837 a space-efficient solution, providing Continuous 14A Load Capability accurate power delivery for low output voltage Programmable Switching Frequency up to 1.5MHz applications. Internal Digital Soft-Start IR3837 is a versatile regulator which offers Enable Input with Voltage Monitoring Capability programmability of switching frequency and Hiccup Mode Over Current Protection current limit while operates in wide input and Internal LDO output voltage range. External Synchronization Enhanced PreBias Start up The switching frequency is programmable from External Reference for Margining Purposes 250kHz to 1.5MHz for an optimum solution. Input for Tracking Applications It also features important protection functions, Integrated MOSFET Drivers and Bootstrap Diode such as Pre-Bias startup, hiccup current limit and o o Operating Junction Temp: -40 C <Tj<125 C thermal shutdown to give required system level Thermal Shut Down security in the event of fault conditions. Power Good Output with Tracking Capability Over Voltage Detection Feature IR3837 offers margining capability through Vref Pin Compatible with 6A and 10A Versions pin. During the margining operation, PGood Small Size 5mmx6mm PQFN, 0.9 mm Height tracks Vref via feedback to ensure correct status Lead-free, Halogen-free and RoHS Compliant of the output voltage. The internal LDO enables the device to operate Applications from a single supply. This internal LDO can be Netcom and Telecom Applications bypassed when an external bias voltage is Data Center Applications available. Distributed Point of Load Power Architectures Fig. 1.
