Infineon Technologies AG DC-DC Converters, Integrated POL Voltage Regulators IR3889MTRPBF

Description
OptiMOS™ IPOL 30 A single – voltage synchronous buck regulator The IR3889 OptiMOSTM IPOL is an easy-to-use, fully integrated DC-DC buck regulator. The onboard PWM controller and OptiMOS™ MOSFETs with integrated bootstrap diode make the IR3889 a small footprint solution, providing high-efficient power delivery. Furthermore, it uses a fast Constant-On-Time (COT) control scheme, which simplifies the design efforts and achieves fast control response. Summary of Features Single 4.3 V to 17 V application or wide input voltage range from 2.0 V to 17 V with an external VCC Precision reference voltage (0.8 V +/- 0.5%) Enhanced fast COT engine stable with ceramic output capacitors and no external compensation Optional forced continuous conduction mode and diode emulation for enhanced light load efficiency Programmable switching frequency from 600 kHz to 2 MHz Monotonic start-up with four selectable soft-start time & enhanced pre-bias start-up Thermally compensated internal over-current protection with four selectable settings Enable input with voltage monitoring capability & power good output Thermal shut down Operating temperature: -40°C < Tj < 125°C Small size: 5 mm x 6 mm PQFN Lead-free, halogen-free and RoHS2 compliant with Exemption 7a Potential Applications Server applications Storage applications Telecom and Datacom applications Distributed Point-of-Load power architectures Applications 48 V power distribution Body electronics and lighting Edge server solutions General purpose motor drive - variating frequency and voltage Telecommunication infrastructure Designers who used this product also designed with TDA21570 | Integrated Smart Power Stages IR38164M | Integrated POL Voltage Regulators IR35215MTRPBF | Digital Multiphase Controllers BSC018NE2LS | N-Channel Power MOSFET TDA21535 | Integrated Smart Power Stages TDA21472 | Integrated Smart Power Stages TDA21520 | Integrated Smart Power Stages TDA21590 | Integrated Smart Power Stages XDPE15284D-0000 | Digital Multiphase Controllers XDPE152C4D-0000 | Digital Multiphase Controllers XDPE12284C-0000 | Digital Multiphase Controllers TDA38640-0000 | Integrated POL Voltage Regulators IR3883MTRPBF | Integrated POL Voltage Regulators PXM1310CDM-G003 | Digital Multiphase Controllers IRFH8201 | N-Channel Power MOSFET BSL308C | Dual MOSFET TDA21570 | Integrated Smart Power Stages IR38164M | Integrated POL Voltage Regulators IR35215MTRPBF | Digital Multiphase Controllers BSC018NE2LS | N-Channel Power MOSFET TDA21535 | Integrated Smart Power Stages TDA21472 | Integrated Smart Power Stages TDA21520 | Integrated Smart Power Stages TDA21590 | Integrated Smart Power Stages 1 2 3 4
