Additional Infomation About Product

MP4570 3A, 4.5V-55V Input, Frequency Programmable, Fully Integrated Synchronous, Step-Down Converter The Future of Analog IC Technology DESCRIPTION FEATURES The MP4570 is a frequency programmable step- Wide Input Voltage Range: 4.5V to 55V down switching converter with integrated internal 90m and 70m Internal High and Low high-side and low side power MOSFETs. It can Power MOSFETs provide 3A continuous output current with peak Peak Current Mode Control current control for excellent transient response Programmable Switching Frequency and efficiency performance. Stable Independent on Output Capacitors Optional External Soft Start The wide 4.5V to 55V input voltage range OCP Protection with Valley Current accommodates a variety of step down applications, including those applications in Detection industrial, PoE, automotive and printer with DC Support External SYNC Clock high voltage bus. OVP Protection Current Limit Decreasing during Output The MP4570 uses peak current mode control to Short for Better Thermal Performance regulate the output voltage. The chip provides Power Good Indication over current protection with valley current Thermal Shutdown Protection detection which is used to avoid current running Available in a TSSOP-20 EP Package. way. Also it has accurate and reliable over voltage protection, and auto recovery thermal APPLICATIONS protection. In addition, the optional external soft PoE Input Non-isolated Buck start is available. Enable and power good Industrial Power Systems indication function can be used to power track easily. In order to increase the efficiency, Printers and Scanners MP4570 will automatically scaling down the Automotive Power Systems switching frequency when load is light. Distributed Power Systems Meanwhile, the low side MOSFET will be turned All MPS parts are lead-free, halogen free, and adhere to the RoHS off to reduce driver loss when zero inductor directive. For MPS green status, please visit MPS website under Quality Assurance. current is detected. MP4570 also features as a MPS and The Future of Analog IC Technology are Registered fully integrated solution with both high side and Trademarks of Monolithic Power Systems, Inc. low side power MOSFETs. Synchronous operation mode with integrated low side MOSFET is much helpful to reduce the conduction loss and also beneficial to reduce external components space and save the cost. The MP4570 is available in a TSSOP-20 EP with exposed pad package. MP4570 Rev. 1.01 www.MonolithicPower.com 1 1/4/2017 MPS Proprietary Information. Patent Protected.
