China Resources Converse launches PT4115 green lighting LED light driver circuit
China Resources Converse Technology (Shanghai) Co., Ltd. newly launched PT4115 green lighting LED lamp driver circuit. PT4115 is a continuous inductor current conduction mode buck constant current source, it has a wide DC 8V to 30V input voltage range, breakdown voltage >45V, output 200mA - 1200mA constant DC, can meet the drive lighting 1 -7 high-power LEDs in series or N low-power LEDs connected in series and parallel, the constant current size can be set according to the application scheme.
PT4115 uses frequency jitter technology to effectively improve EMI; PWM dimming from full-scale down to zero, safe and reliable, dimming ratio up to 5000:1; SOT89-5 package, chip die (Die) Thermal conduction is very effective by dissipating heat directly from the metal plate (ExposedPAD) outside the package. The over temperature protection function (TSD) is set inside the PT4115 to ensure stable and reliable operation of the system. When the IC chip temperature exceeds 160 °C, the IC will enter the TSD protection state and stop the current output, and when the temperature is lower than 140 °C, the IC will return to the working state.
The PT4115 can use the principle of analog dimming and the negative feedback of temperature on the LED current to realize the dynamic temperature control of the LED lamp. Just add a thermistor or PN junction at the dimming end (DIM). Plus the rectifier bridge PT4115 can be applied to AC 12V, 24V power supply LED lamps. The application of the PT4115 is very simple, with only four peripheral parts. With a working efficiency of 97%, the PT4115 is a true green driver IC. PT4115 is widely used in various types of LED lamps such as MR11, MR16, water lamps and street lamps that use LED lamps.
In order to effectively shorten the design cycle of LED luminaire manufacturers, China Resources Converse's one-step promotion model provides LED luminaire manufacturers with DEMO boards, circuit diagrams, PCB boards and BOMs that can be directly used for MR16 production, providing timely and timely use for customers. Thoughtful technical support.
