Embodiment 1

[0049] Take the AC-DC chip module 100' in the chip integrated module as an example, such as figure 1 As shown, since the AC-DC chip module 100' usually only has a single ground common pin, the filter 210' needs to be connected to the input end of the AC-DC chip module 100', that is, the AC side of the AC-DC chip module 100'. Based on capacitor withstand voltage and safety considerations, the filter 210' needs to use a safety capacitor CX1 (such as an X safety capacitor). However, the safety capacitor CX1 has a high cost and a large volume, which causes the AC-DC chip module to be connected to the filter 210 'The rear volume and cost have increased substantially. For this reason, there is an urgent need for a new chip integrated module, which will not greatly increase the volume and cost after meeting the increased functional requirements of the product.

[0050] Such as figure 2 As shown, the embodiment of the present invention provides a chip integrated module 100, includi...

Embodiment 2

[0064] In the prior art, in order to set the over-temperature protection threshold, refer to figure 1 , a control pin TH is required to connect an external resistor Rth, and the slope of the temperature-current curve can remain unchanged. If it is necessary to adjust the temperature-current curve line, an additional control pin needs to be set and another resistor is externally connected, that is, chip integration in the prior art As the function of the module 100 ′ increases, the number of pins is bound to increase, but the package structure usually has a limit on the number of pins. The above-mentioned embodiment 1 of the present invention introduces that the first control pin TH and the second control pin SLP can be multiplexed, and when the first external resistor Rth and the second external resistor Rslp are multiplexed, the chip integrated module 100 can determine the over-temperature protection threshold and temperature-current curve slope, which can reduce the number o...

Embodiment 3

[0073] Such as Figure 4 As shown, the embodiment of the present invention provides a control circuit 200, including a filter 210 and the chip integrated module 100 mentioned in the first embodiment above. Wherein, the filter 210 may be an EMI filter, or other types of filters.

[0074] The filter 210 includes a first inductor L2 and a first capacitor EC1. The first inductor L2 is used for filtering, and its two ends are respectively connected to the second ground pin GND2 and the first ground pin GND1 of the chip integrated module 100, and the second ground pin GND2 and the first ground pin GND1 are respectively grounded, the positive pole of the first capacitor EC1 is connected to the supply voltage input pin VIN, and the negative pole of the first capacitor ECI is connected to the second ground pin GND2.

[0075] In the embodiment of the present invention, the first capacitor EC1 of the filter 210 is arranged between the supply voltage input pin VIN and the first ground pi...

Abstract

The invention provides a chip integration module, a control circuit and a lighting device. The chip integration module comprises an alternating current input pin, a second grounding pin, a first grounding pin, a rectification unit, a power supply voltage input pin and a logic control unit, the alternating current input pin is connected with a rectification input end, the first grounding pin is connected with a common reference end, and the second grounding pin is connected with the logic control unit; and the supply voltage input pin is connected with the rectification output end. The chip integration module is provided with two grounding pins. Therefore, when the filter is connected on the basis of the chip integration module, the first inductor of the filter can be connected between twogrounding pins, and the first capacitor of the filter is arranged between the power supply voltage input pin and the first grounding pin, i.e., the first capacitor of the filter is arranged at the rear end of the rectification unit, so that the filter can realize a filtering effect by using an electrolytic capacitor or a thin-film capacitor instead of a safety capacitor.

Description

technical field [0001] The present application relates to the technical field of chip integration, in particular to a chip integration module, a control circuit and a lighting device. Background technique [0002] In the application of lighting products, the functional requirements of the control circuit in lighting products are getting higher and higher. For example, after meeting the AC-DC (Alternating Current, AC current-Direct Current, DC current) conversion, it is also necessary to meet the electromagnetic compatibility requirements of the product. Require. [0003] Take the AC-DC chip module 100' in the chip integrated module as an example, such as figure 1 As shown, since the AC-DC chip module 100' usually only has a single ground common pin, the filter 210' needs to be connected to the input end of the AC-DC chip module 100', that is, the AC side of the AC-DC chip module 100'. Based on capacitor withstand voltage and safety considerations, the filter 210' needs to ...
