EV0021 Datasheet (ETC) - High Efficiency White LED Driver

EV0021, High Efficiency White LED Driver

The MP1521 is a constant-current Boost Regulator.

This IC has three individual current-sensing feedbacks, which are ideal for driving multiple strings of series connected LEDs.

The OLS pin is designed for detecting loose or open LED connections.

The IC uses a peak current, constant minimum off-time
