CURRENT LED DRIVER



DESCRIPTION

The UTC UPSL103 is a highly-integrated, low startup current,

average current mode, one cycle control PFC and fixed switching

frequency PWM controller. These functions enable the LED driver to

easily meet the accuracy average LED current and high power factor

requirements.

The UTC UPSL103 also features a 45kHz fixed frequency

oscillator, an internal 200mV precision reference, and a PWM

comparator with latching logic. The accurate output LED current is

achieved by an averaging current feedback loop and the LED current

dimming can be easily controlled via the DIM pin. The UTC UPSL103

also has multiple features to protect the controller from fault

conditions, including Under Voltage Lockout (UVLO), Over Current

Protection (OCP) and Over Voltage Protection (OVP). Additionally, to

ensure the system reliability, the UTC UPSL103 is built with the

thermal protection function.

The UTC UPSL103 improves the performance and reduces the

cost of the LED driver.
