Additional Infomation About Product

MP4558 1A, 2MHz, 55V Step-Down Converter DESCRIPTION FEATURES The MP4558 is a high-frequency, step-down Wide 3.8V-to-55V Operating Input Range switching regulator with an integrated internal 250m Internal Power MOSFET high-side high-voltage power MOSFET. It Up to 2MHz Programmable Switching provides up to a 1A output with current-mode Frequency control for fast loop response and easy 140A Quiescent Current compensation. Stable with Ceramic Capacitors Internal Soft-Start The wide 3.8V-to-55V input range accommodates Up to 95% Efficiency a variety of step-down applications, including automotive input. A 12A shutdown-mode supply Output Adjustable from 0.8V to 52V current makes it suitable for battery-powered Available in SOIC8E and 3mm x 3mm applications. QFN10 Packages A scaled-down switching frequency in light-load APPLICATIONS conditions provides high power-conversion High-Voltage Power Conversion efficiency over a wide load range while reducing Automotive Systems switching and gate driver losses. Industrial Power Systems The frequency fold-back prevents inductor current Distributed Power Systems runaway during startup and thermal shutdown Battery Powered Systems provides reliable, fault-tolerant operation. All MPS parts are lead-free and adhere to the RoHS directive. For MPS green status, please visit the MPS website under Products, Quality Assurance By switching at 2MHz, the MP4558 can prevent page. EMI (electromagnetic interference) noise MPS and The Future of Analog IC Technology are registered trademarks of problems, such as those found in AM radio and Monolithic Power Systems, Inc.
