Description

This is Step-Down Converter. MP1583 Step-Down The Future of Analog IC Technology 3A, 23V, 385KH- Converter DESCRIPTION The MP1583 is a step -down regulator with a built-in internal Power MOSFET. It achieves 3A of continuo us output current over a wide input supply range with excellent load and line regulation. Current mo de operatio n provides f ast transien t response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting a nd thermal shutdown. An adjustab le soft-start reduces the stress on the input source at startup. In shutdown mode the regulator dr aws 20 μA of supply current. The MP158 3 requires a minimu m number of external components, providing a compact solution. FEATURES 3A Output Current Programma ble Soft-Start 100m Ω Internal Power MOSFET Switch Stable with Low ESR Outpu t Ceramic Ca pacitors Up to 95% Efficiency 20 μA Shutdown Mode Fixed 385KH- Frequency Thermal Shutdown Cycle-by-Cycle Over Current Protection Wide 4.75V to 23V Operat.
