Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the structural representation of the utility model television set Switching Power Supply.
Fig. 2 is to use the structural representation of television set power supply circuits of the Switching Power Supply of Fig. 1.
Embodiment
As shown in Figure 1, in the embodiment of television set Switching Power Supply of the present utility model, the television set Switching Power Supply comprises main switch power supply 2, auxiliary switch power supply 1, relay 3, pressurizer 4 and power supervisor 5.Wherein the input of main switch power supply 2 and auxiliary switch power supply 1 is coupled in the input of television set external connection power supply simultaneously, gives two groups of Switching Power Supply power supplies.The output of main switch power supply is that the output of first voltage is mainly used in the TV MCU power supply; The output of auxiliary switch power supply 1 is second output, and second output and the coupling of relay 3 inputs, the output of relay 3 is coupled to the control end of main switch power supply, and second output also is coupled to the power supply port of power supervisor 5 behind process pressurizer 4; The control end of relay 3 is coupled in the control output of power supervisor, and its break-make is controlled.For example, wherein main switch power supply and prior art main switch power supply commonly used is identical, and the auxiliary switch power supply uses ACT34, and input voltage is 110-240V, and output voltage is 9V to the maximum, and output current is 50mA to the maximum.Power management module uses chips W T6701F, and by the power supply of auxiliary switch power supply, pressurizer 4 uses three terminal regulator 78L05.When described Switching Power Supply being used for the television set power supply, its power supply circuits embodiment as shown in Figure 2.
In the television set power supply circuits embodiment of the Switching Power Supply shown in Figure 1 of the use shown in Fig. 2, the input of main switch power supply 2 and auxiliary switch power supply 1 is coupled in the input of television set external connection power supply simultaneously, the output of main switch power supply (voltage output one) is coupled to television set microcontroller (MCU) 6, is used for to 6 power supplies of television set microcontroller; The output of auxiliary switch power supply (voltage output two) is coupled with the input of relay 3, and the output of relay 3 is coupled to the control end of main switch power supply 2; The output of auxiliary switch power supply 1 receives 7 and the power supply port of power supervisor 5 through being coupled to TV remote-control behind the three terminal regulator 4; The control output that remote control receives head is connected to television set microcontroller 6 and power supervisor 5; Power supervisor 5 by with the control connection of television set microcontroller 6 and relay 3, the two is controlled.Wherein each element of Switching Power Supply can use with Fig. 1 in the identical configuration of each element.Also can receive in described remote control 7 and power supervisor 5 between the crystal diode 8 that also is connected in series pass through to intercept negative pulse.
When the television set operate as normal, the conducting of power supervisor control relay, main switch power supply 2 is connected, to TV MCU 6 power supplies; When standby, the power supervisor control relay ends, turn-off the power supply of main switch power supply, auxiliary switch power work only, the 9V voltage one tunnel that the auxiliary switch power supply provides is for relay usefulness, no current when standby, another road receives head and power supervisor use through three terminal regulator for remote control, total standby current be no more than 5mA, so be exactly the loss of stand-by power consumption auxiliary switch power supply can reach below the 1W fully.
