NON-ISOLATED BUCK
OFFLINE LED DRIVER
DESCRIPTION
The UTC USL3631 is a high performance, high precision and
low cost constant current LED driver for non-isolated buck
application. The device operates in critical conduction mode and
is suitable for 85V~265V universal input offline LED lighting. It
operates in critical conduction mode, the output current does not
change with the inductance and LED output voltage.
The UTC USL36313 integrates a 600V power MOSFET. It can
achieve excellent constant current performance with very few
external components, so the system cost and size are minimized.
The UTC USL3631 offers rich protection functions to improve
the system reliability, including LED open circuit protection, LED
short circuit protection, VCC under voltage protection, CS resistor
short circuit protection and thermal regulation function.
FEATURES
* Critical conduction mode operation
* Internal 600V Power MOSFET
* Ultra low operating current
* No auxiliary winding
* ±5% LED output current accuracy
* LED short protection
* LED open protection
* VCC under voltage protection
* Current sensing resistor short protection
* Thermal regulation function
