MP2370DJ-LF-P Monolithic Power Systems

MP2370 1.2A, 24V, 1.4MHz Step-Down White LED Driver The Future of Analog IC Technology DESCRIPTION FEATURES 1.2A Peak Output Current The MP2370 is a monolithic step-down white 0.35 Internal Power MOSFET Switch LED driver with a built-in power MOSFET. It Stable with Low ESR Output Ceramic achieves 1.2A peak output current over a wide Capacitors input supply range with excellent load and line Also Work with Cap-less Configuration regulation. Current mode operation provides Up to 87% Efficiency fast transient response and eases loop 0.1 A Shutdown Mode stabilization. Fault condition protection includes Fixed 1.4MHz Frequency cycle-by-cycle current limiting and thermal Thermal Shutdown shutdown. Cycle-by-Cycle Over Current Protection Wide 4.5V to 24V Operating Input Range The MP2370 requires a minimum number of 0.15V Sense Voltage readily available standard external components. Available in a TSOT23-6 Package and a The MP2370 is available in a TSOT23-6 package TQFN-6 (2mmx2mm) package and a TQFN-6 (2mmx2mm) package.
