IR3889MTRPBF

Brand: Infineon(英飞凌)

product Model: IR3889MTRPBF

Description : IR3889 is an easy-to-use fully integrated DC-DC buck regulator. Onboard PWM controller and OptiMOS with integrated bootstrap diode ™ FET makes IR3889 a small-sized solution that enables efficient power transmission. In addition, it adopts a fast constant on-time (COT) control scheme, which simplifies the design work and achieves fast control response. IR3889 has an internal low dropout regulator that allows for single power supply. It can also operate with an external bias power supply, and its operating input voltage (PVin) range is extended to 2.0 V to 17 V. IR3889 is a multifunctional regulator that offers programmable switching frequencies from 600 kHz to 2 MHz, four optional current limits, four optional soft start times, forced continuous conduction mode (FCCM), and diode simulation mode (DEM) operation. It also has important protection functions, such as pre bias start, thermal compensation current limit, overvoltage and undervoltage protection, and thermal shutdown function, which can provide the required system level safety guarantee under fault conditions.
