MP9841GL-P Monolithic Power Systems

MP9841 36V, 1A, Low I , Q Synchronous Step-Down Converter DESCRIPTION FEATURES 2A Low Shutdown Supply Current The MP9841 is a high-frequency, synchronous, 14A No-Load Quiescent Current rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very Internal 125m High-Side and 115m Low- Side MOSFET compact solution that achieves 1A of continuous output current with excellent load 350kHz to 2.5MHz Programmable Switching and line regulation over a wide 3.3V to 36V Frequency input supply range. The switching frequency Power Good (PG) Output can be programmed or synchronized to an External Soft Start (SS) external clock in the range of 350kHz to 80ns Minimum On Time 2.5MHz. The synchronous operation and ultra- Selectable Forced CCM and AAM low 14A sleep mode quiescent current provide Low Dropout Mode high efficiency over the output current load Hiccup Over-Current Protection (OCP) range, allowing the MP9841 to be used in a Available in a QFN-16 (3mmx4mm) variety of step-down applications in automotive Package input environments and battery-powered applications. APPLICATIONS Peak-current-mode operation provides fast Automotive Systems transient response and eases loop stabilization. Industrial Power Systems The excellent low dropout performance allows All MPS parts are lead-free, halogen-free, and adhere to the RoHS the MP9841 to be used in high duty cycle directive. For MPS green status, please visit the MPS website under Quality Assurance. MPS and The Future of Analog IC Technology are applications. registered trademarks of Monolithic Power Systems, Inc. Full protection features include over-current protection (OCP), short-circuit protection (SCP), and thermal shutdown. An open-drain power good (PG) signal indicates when the output is within 10% of its nominal voltage. The MP9841 is available in a space-saving QFN-16 (3mmx4mm) package.
