AX3123-23V,1.8A,1.4MHz Step-Down DC-DC停产 |
AX3123-23V,1.8A,1.4MHz Asynchronous Step-Down DC-DC Converter DataSheet (2015年7月停产)
GENERAL DESCRIPTION The AX3123 is a monolithic step-down switch mode converter with a built-in power MOSFET. It achieves 1.8A 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 limit and over temperature protection. The AX3123 requires a minimum number of available standard external components. The AX3123 is available in SOT-23-6L, TSOT-23-6L packages
FEATURES - 1.8A Output Current - 180mΩ Internal Power MOSFET Switch - Stable with Low ESR Output Ceramic Capacitors - Up to 92% Efficiency - Fixed 1.4MHz Frequency - Current Mode Operation - Over-Temperature Protection with Hiccup-Mode - Cycle-by-Cycle Over Current Protection - Wide 4.5V to 23V Operating Input Range - Output Adjustable from 0.805V to 15V - 10μA Shutdown Current - Miniature Packages: SOT-23-6L and TSOT-23-6L
