MPM3805A 6V Input, 0.6A Module, Synchronous, Step-Down Converter with Integrated Inductor AEC-Q100 Qualified The Future of Analog IC Technology DESCRIPTION FEATURES The MPM3805A is an automotive grade, step- Guaranteed Industrial/Automotive Temp down module converter with built-in power Wide 2.6V to 6V Operating Input Range MOSFETs and an inductor. The modules Adjustable Output from 0.6V integrated inductor simplifies the power system Up to 0.6A Peak Output Current design and provides easy and efficient use. The 100% Duty Cycle in Dropout DC/DC module comes in a small surface- Forced CCM Mode mounted QFN-12 (2.5mmx3.0mmx0.9mm) EN and Power Good for Power Sequencing package and achieves 0.6A of peak output Cycle-by-Cycle Over-Current Protection current from a 2.6V to 6V input voltage range (OCP) with excellent load and line regulation. The Short-Circuit Protection (SCP) with Hiccup output voltage can be regulated as low as 0.6V. Mode Only FB resistors and input and output Only Four External Components Required: capacitors are needed to complete the design. Two Ceramic Capacitors, Two FB Divider The constant-on-time control (COT) scheme Resistors provides fast transient response and eases loop Available in a QFN-12 (2.5mm x 3.0mm x stabilization. Fault condition protection includes 0.9mm) Package cycle-by-cycle current limiting and thermal Total Solution Size 6mmx3.8mm shutdown. Available in AEC-Q100 The MPM3805A is ideal for a wide range of APPLICATIONS automotive applications, including small ECUs, Automotive ECU camera modules, telematics, and infotainment Rear Cameras systems. E-Call Telematics Infotainment Systems All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For MPS green status, please visit the MPS website under Quality Assurance.
