Rate, and then control output voltage.So the primary side winding Np and secondary side winding Ns of flyback transformer are not simultaneously turned on.
The work of chip is divided into three kinds of mode of operations：Fixed frequency modes, CC（Constant current）Pattern, CV（Constant pressure）Pattern.When
FB voltages VFB<During 0.5V, fixed frequency modes are operated in（38KHz）, 0.5V<VFB<During 2V（Vref1=2V）, switch to CC works
Operation mode.Chip startup stage switches to CV working conditions when completing, and when load continues increase, system back switches to CC works
Operation mode.
When chip is started working, fixed frequency control signal driving Q1 and M1 conductings, input voltage is carried in primary side winding
Both ends, the referred to as conducting of primary side branch road, conducting phase.Primary current is gradually increasing, current detecting end（CS）Voltage is gradually increasing, when
When it rises to internal reference voltage Vref2, peak current detection comparator output switching activity, Q1, M1 are turned off, and secondary side winding is led
Logical, energy release, demagnetization phase starts.
In demagnetization phase, output voltage is reflected on primary side assists winding Naux with certain proportion, is divided through resistance R1, R2
Pressure, it is sent into pressure feedback port（FB）.Again by sampling hold circuit, the voltage at demagnetization phase 3/4 is obtained（Voltage herein is more
Add accurately reaction output voltage）, and reference voltage is together sent into error amplifier.Ladder raised voltage is produced by oscillator,
Through PFM pulse frequency modulateds, frequency control signal is produced, controls drive circuit.

Voice synchronization wire jumper operates.When device end changes or other reasons cause change wire jumper, system can automatically generate job note,
The each wire jumper change at scene is instructed, makes network topology structure and is expected consistent.
Job note can also be distributed to the electronic wiring frame specified by system, make the wire jumper of the distributing frame pre- according to job note
The result change of phase, and there is any exception all to alert.When because hardware fault or power-off occurs in certain reason, in failure
After excluding or being powered, electronic wiring frame and its corollary system can automatic detection current information whether with before failure or before power-off
Information is consistent.If inconsistent, field controller will alarm, simultaneous computer management module can also be made anti-in real time
Should, keeper is prompted by the state before link information renewal to failure or power-off., will be with after the determination for obtaining keeper
The form of job note instruct Field Force by link-recovery to power-off before or failure before, it is ensured that the accuracy of current link information and
Operability.Often there are hundreds and thousands of wire jumpers in the scene of comprehensive wiring a, rack, how to pass through the one of some wire jumper
It is always a problem that end, which rapidly finds out the other end, and RFID electronic wiring frames but can easily solve this problem.
One tracking card is placed on that port that user requires to look up, the port and its port that is connected to
LED lamps will flash, and can quickly find current ink.RFID electronic wiring frame systems have multi-level alarm function.First,
When any link illegally changes, electronic wiring frame can all be found in real time, and be alerted by LED lamps, and alarm is believed
Breath is sent to controller.Controller can send instruction display alarm content and simultaneous voice prompting on screen, and alarm is believed
