The Future of Analog IC Technology MP1593 3A, 28V, 385kHz Step-Down Converter DESCRIPTION The MP1593 is a step-down regulator with an internal Power MOSFET. It achieves 3A of continuous output current over a wide input supply range with excellent load and line regulation. Current mode operation provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. An adjustable soft-start reduces the stress on the input source at startup. In shutdown mode the regulator draws 20µA of supply current. The MP1593 requires a minimum number of readily available external components, providing a compact solution. EVALUATION BOARD REFERENCE Board Number EV1593DN-00A Dimensions 2.1”X x 1.3”Y x 0.
