Customers can easily avail this LED driver from us at nominal rates. Once the output of comparator goes high, the GATE output goes low. Due to the critical work in the inductor current continuous mode, power MOS at zero current turn state, the switching losses can be reduced, while the utilization of the transformer is higher. 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. Mobile Number Please enter Mobile Number. The driver operates in critical conduction mode, the output current does not change with the inductance and LED output voltage.

Once LED short circuit or LED open circuit is detected, the system enters into low standby mode in which the system consumes very low power and the output status is monitored continuously. The chip limits the maximum system frequency np3108 the minimum system frequency to ensure the system stability.
This control method also achieves excellent line and load regulation. Customers can easily hp3108 this LED driver from us at nominal rates. Please enter Mobile Number.
LED Driver – BP Integrated Circuits Distributor / Channel Partner from Mumbai
Our LED driver is designed with set standards with the help of skilled professionals using high-end technology and quality-proven components. The chip goes back to normal operation automatically after the abnormal situation is removed. Compare Quotations le seal the deal. Once the output of comparator goes high, the GATE output goes low.
Supply Voltage 5 V. The BPMB adopts proprietary primary side current sensing scheme. For the parameters without minimum and maximum value in the EC table, the typical value defines the operation range, the accuracy is not guaranteed by spec. The system reliability is further improved by the thermal regulation function.
Line voltage compensation coefficient can also be flexibly adjusted by external components. The output current is reduced when the controller is over temperature. The inverting terminal of comparator is tied to an internal mV reference.
The CS is connected to non-inverting inputs of the current sense comparator.
