EV4575-F-00A 5A, 55V, Frequency Programmable Synchronous, Step-Down Converter The Future of Analog IC Technology DESCRIPTION FEATURES The EV4575-F-00A is an evaluation board for the Wide Input Voltage Range: 4.5V to 55V MP4575, a frequency programmable step-down Programmable Switching Frequency switching converter with integrated internal high- Optional External Soft Start side and low side power MOSFETs. It can Peak Current Mode Control provide 5A continuous output current with peak OCP Protection with Valley Current current control for excellent transient response Detection and efficiency performance. Support External SYNC Clock The wide 4.5V to 55V input voltage range OVP Protection accommodates a variety of step down Current Limit Decreasing during Output applications, including those applications in Short for Better Thermal Performance industrial, PoE, automotive and printer with DC Power Good Indication high voltage bus. Thermal Shutdown Protection The valley current detection is used to avoid Fully Assembled and Tested current running way at over current protection. APPLICATIONS Also it has accurate and reliable over voltage protection, and auto recovery thermal protection. PoE Input Non-isolated Buck In addition, the optional external soft start is Industrial Power Systems available. Enable and power good indication Printers and Scanners function can be used to power track easily. In Automotive Power Systems order to increase the efficiency, MP4575 will Distributed Power Systems automatically scaling down the switching All MPS parts are lead-free and adhere to the RoHS directive. For MPS green frequency when load is light. Meanwhile, the status, please visit MPS website under Quality Assurance. MPS and The low side MOSFET will be turned off to reduce Future of Analog IC Technology are Registered Trademarks of Monolithic Power Systems, Inc. driver loss when zero inductor current is detected. 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 MP4575 is available in a TSSOP-20 EP with exposed pad package.
