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
