Infineon Technologies AG DC-DC Converters, Integrated POL Voltage Regulators TDA38840

OptiMOS™ integrated point-of-load 40 A single output high efficiency buck regulator The TDA38840 OptiMOS™ IPOL 40 A is an easy-to-use, fully integrated DC-DC buck regulator with patented fast Constant-On-Time (COT) control scheme. It simplifies the design effort, while enabling an enhanced transient response and improved Vout regulation. The onboard PWM controller and OptiMOS™ 5 MOSFETs with integrated bootstrap diode make the TDA38840 a small footprint, high efficiency solution for various point-of-load applications. Summary of Features Wide input voltage range from 2.0 V to 17 V Precision reference voltage (0.6 V +/- 0.5%) Compensation free enhanced COT engine Optional forced continuous conduction mode and diode emulation for enhanced light load efficiency Programmable switching frequency from 600 kHz to 2 MHz Selectable soft-start time Enhanced pre-bias start-up Selectable OCP limit Enable input with voltage monitoring capability Power Good output Thermal shut down Operating temp: -40 °C < Tj < 125 °C Small Size: 5 mm x 6 mm PQFN Halogen-free and RoHS2 compliant with exemption 7a Benefits Easy to use fast Constant On-Time PWM Engine High efficiency Accurate output voltage regulation Superior transient response Low BOM Potential Applications Server applications Storage applications Telecom and Datacom applications Distributed Point-of-Load power architectures Artificial intelligence Applications 48 V intermediate bus converter (IBC) Consumer electronics Edge computing Telecommunication infrastructure Wireless Communication Designers who used this product also designed with TDA21520 | Integrated Smart Power Stages SLB 9670VQ2.0 | OPTIGA™ TPM - Trusted Platform Module XDPE12284C-0000 | Digital Multiphase Controllers IPB020N10N5LF | N-Channel Power MOSFET IPB033N10N5LF | N-Channel Power MOSFET TDA21535 | Integrated Smart Power Stages TDA21520 | Integrated Smart Power Stages SLB 9670VQ2.0 | OPTIGA™ TPM - Trusted Platform Module XDPE12284C-0000 | Digital Multiphase Controllers IPB020N10N5LF | N-Channel Power MOSFET IPB033N10N5LF | N-Channel Power MOSFET TDA21535 | Integrated Smart Power Stages TDA21520 | Integrated Smart Power Stages SLB 9670VQ2.0 | OPTIGA™ TPM - Trusted Platform Module 1 2
