XD9057
High Voltage LED Lighting Driver
DESCRIPTION
XD9057 is an LED driver with high voltage switches which
can be powered directly from the 110V/220V AC Mains.
With the internal dual negative feedback mechanism, the
average current of the LED does not vary with changes in
external parameters like temperature and the input voltage.
It performances high PF, high efficiency, and extra low EMI
spikes at the same time. The output power can be adjusted
by an external resistor. XD9057 features high-precision zero
temperature coefficient of the reference voltage, over
voltage protection, over temperature protection, under
voltage lockout and other functions. It has significant
advantages in the applications of tube light, ceiling light,
and etc..
Typical Application Circuit
FEATURES
Driven directly from AC lines, power 7W-15W LED.
High performance in Power factor (>0.95) with high
efficiency.
Optimized EMI characteristics eliminate additional
EMI filter components.
