产 品 说 明 | ||||||||
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. FEATURES * High power factor by one cycle control * Accuracy and programmable constant current * Low BOM cost * Dimmable LED current by DIM * Average current / fixed frequency control * Gate output voltage clamp * LED Open Protection * LED Short Protection * Over Current Protection * Built-in thermal protection 规格书UPSL103 |
