BP3108 LED DRIVER DOWNLOAD

And the line compensation factor can also be tuned externally for flexibility. Our offered LED drivers are obtainable from us in numerous stipulations as per the need of customers. Current sense CS resistor The CS resistor ground should be as close to the chip ground as possible to reduce the ground noise coupled, which improves the quality of the sensing signal. Few external components are required to achieve wide triac dimming range and good dimming effect without visible flicker. The comparator is constantly comparing the CS voltage to the internal mV. Human Body mode, pF capacitor discharge on 1.

Krishna Led Lighting Semiconductors. Once LED short circuit or LED open circuit is detected, the system enters into low standby mode bp33108 which the system consumes very low power and the output status is monitored continuously. The FB sense threshold is 1V. The inverting terminal of comparator is tied to an internal mV reference.

During normal operation, The Vcc is supplied via the auxiliary winding. BP proprietary current sampling mechanism, work on the primary side feedback mode, without secondary feedback circuitry to achieve highly accurate output current control, saving system cost and size, to improve the reliability of the system.

Line voltage compensation coefficient can also be flexibly adjusted by external components. Pulsar Electronics Private Limited No.

For the parameters without minimum and maximum value in the EC table, the typical value defines the operation range, the bp33108 is not guaranteed by spec. Save time and let us provide you with verified contacts.

The patented triac dimming control and phase detect technology is compatiable to most triac dimmer. The BPMB utilizes patented line and load voltage compensation method to achieve excellent line and load regulation. The electrical characteristics table les the operation range of the device, the electrical characteristics is assured on DC and AC voltage by test program.

BP is assembled in SOP-8 package. Please enter your Email ID. The patented control method dramatically saves the system cost and size by eliminating all secondary feedback circuitry and loop control compensation circuitry. Welding DS EN Furthermore, our offered LED driver is checked from our side before delivered it in the market. BP integrates the triac dimming control circuit internally. BP is a single-stage, high-precision with active power factor correction PSR LED constant current control chip, with dimming control function for the full range of 85VacVac input voltage isolated flyback or buck Non-isolated LED constant current power supply.

Human Body mode, pF capacitor discharge on 1. The operation frequency is given by: We are here to help!
