Datasheet Summary
Universal High Brightness LED Driver
DESCRIPTION
APPLICATIONS
The BM0550HV is a high efficiency LED driver. It
AC/DC or DC/DC LED driver applications operates in wide range input voltage from 10V up to
Backlighting for flat panel displays
600V. The device drives an external MOSFET at a fixed
General purpose constant current source frequency. The frequency is programmable up to
Automotive
3280KHz with a single resistor. The dimming control for
Chargers chip can be either PWM input or linear input. The
LED string is driven at a constant current without the need for loop pensation. BM0550HV requires only few external ponents to achieve constant LED current...
