PSR SINGLE-STAGE APFC

OFFLINE LED CONTROLLER



DESCRIPTION

The UTC UCL2310 is a high precision primary-side regulation

PWM controller with single stage Active PFC, specially designed

for universal input offline flyback or buck-boost constant current

LED lighting. The controller with on-chip PFC circuit achieves

high power factor and low THD. Operating in critical conduction

mode, the power MOSFET switching loss is reduced and the

inductor is fully utilized.

SOP-8

The UTC UCL2310 adopts proprietary primary side current

sensing scheme. It can precisely control the LED current without

secondary side sense and feedback circuits. The system size

and cost are optimized, as well as the system reliability.

The UTC UCL2310 utilizes patented line and load voltage

compensation method to achieve excellent line and load

regulation. And the line compensation factor can also be tuned

externally for flexibility.

The UTC UCL2310 offers rich protection functions to improve

the system reliability, including LED open circuit protection, LED

short circuit protection, V_CCover voltage protection, V_CCunder

voltage protection, CS resistor open protection and cycle by cycle

current limit. All the protection functions are auto-recovery. The

system reliability is further improved by the thermal regulation

function. The output current is reduced when the controller is

over temperature.


