Wherein, the positive pole of storage battery connects No. 5 pins of chip TL3844BDR-8, No. 6 pins, No. 7 pins, No. 8 pins, one end of the negative pole contact resistance R1 of storage battery, the other end of resistance R1 connects negative pole of output end, negative pole of output end ground connection, No. 1 pin of chip TL3844BDR-8, be connected with one end of inductance L 1 after No. 2 pins are connected, the other end of inductance L 1 connects the positive pole of output, No. 3 pins of chip TL3844BDR-8 connect the one end of electric capacity C1 and the electric capacity C2 be connected in parallel, the electric capacity C1 be connected in parallel is connected with one end of inductance L 1 with the other end of electric capacity C2, the anode of diode D1 connects output head anode, the negative electrode of diode D1 connects No. 4 pins of chip TL3844BDR-8.
Optionally, described Novel steam power supply on vehicle also comprises: protective resistance, and one end of described protective resistance connects the other end of inductance L 1, and the other end of protective resistance is connected with output head anode.
In the utility model embodiment, the technical scheme that the utility model provides provides a kind of Novel steam power supply on vehicle, and it has good hypotensive effect, and it also has good protective effect to automotive electronics, so it has the high advantage of fail safe.
Accompanying drawing explanation
The new automobile power circuit diagram that Fig. 1 provides for the utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model embodiment provides a kind of Novel steam power supply on vehicle, this power supply as shown in Figure 1, comprise: storage battery, chip (concrete model: TL3844BDR-8, producer, Texas Instrument), resistance, electric capacity, diode, inductance, wherein, the positive pole of storage battery connects No. 5 pins of chip TL3844BDR-8, No. 6 pins, No. 7 pins, No. 8 pins, one end of the negative pole contact resistance R1 of storage battery, the other end of resistance R1 connects negative pole of output end, negative pole of output end ground connection, No. 1 pin of chip TL3844BDR-8, be connected with one end of inductance L 1 after No. 2 pins are connected, the other end of inductance L 1 connects the positive pole of output, No. 3 pins of chip TL3844BDR-8 connect the one end of electric capacity C1 and the electric capacity C2 be connected in parallel, the electric capacity C1 be connected in parallel is connected with one end of inductance L 1 with the other end of electric capacity C2, the anode of diode D1 connects output head anode, the negative electrode of diode D1 connects No. 4 pins of chip TL3844BDR-8.
The circuit that the utility model provides is because add chip TL3844BDR-8, when storage battery input voltage is too high, chip TL3844BDR-8 reduces battery tension, then exported by output head anode, thus reduce use voltage, as voltage is too high, then after diode D1 conducting by too high Voltage Feedback to chip TL3844BDR-8, chip TL3844BDR-8 limits passing through of battery tension, play a protective role, so it has reduction battery tension, avoid automotive electronics because overtension damages, so it has reduction voltage, the advantage that fail safe is high.
Optionally, above-mentioned power supply also comprises: protective resistance (not shown in FIG.), and one end of this protective resistance connects the other end of inductance L 1, and the other end of protective resistance is connected with output head anode.This protective resistance can provide overvoltage protection to automotive electronics.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
