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

LED driver with a built-in power MOSFET. It

achieves 1.2A peak 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.

0.35Ω Internal Power MOSFET Switch

Stable with Low ESR Output Ceramic

Capacitors



Also Work with Cap-less Configuration

Up to 87% Efficiency

0.1μA Shutdown Mode

Fixed 1.4MHz Frequency

Thermal Shutdown

Cycle-by-Cycle Over Current Protection

Wide 4.5V to 24V Operating Input Range

0.15V Sense Voltage

Available in a TSOT23-6 Package and a

TQFN-6 (2mmx2mm) package

The MP2370 requires a minimum number of

readily available standard external components.

The MP2370 is available in a TSOT23-6 package

and a TQFN-6 (2mmx2mm) package.

APPLICATIONS
