Tie point connects diode D1 anode；Diode D1 negative electrode meets the feedback end FB of constant pressure driving chip.
Operation principle explanation：
Using stable reference power supply as reference voltage, using R1, R2, R5 partial pressures obtain the voltage equal with FB, so as to
Remove to adjust DCDC IC inside PWM by FB to control the size of output current.For example, working as output current becomes big, in sampling electricity
Voltage on resistance R5 will raise, and because VRFE+ is fixed value, so as to be that FB voltages become big, FB becomes big, and dutycycle will subtract
It is few, so as to be that output current is reduced, and a complete feedback is completed, reach the purpose of stabling current output.
Constant current calculates：
If voltage caused by the overcurrent of R5 upstream is VIo, output current Io
Reference voltage is VREF+=2.5V,
FB voltages are VFB=0.6V,
R5=0.1 Ω, R1=40K Ω, R2=10K Ω
Then：
VIo=Io*R5
VFB=VIo+ ((VREF+-VIo) * R2/ (R1+R2))
Calculate：
Io=(VFB* (R1+R2)-R2*VREF+)/R1*R5
The equation if K=(VFB* (R1+R2)-R2*VREF+)/R1 is taken
Io=K/R5
In terms of calculation formula, Io output currents and output voltage and input voltage do not have any relation, only and VFB.R1,
R2, VREF are relevant, and these parameters are in specific design, they be all it is fixed (VFB be in stable state it is fixed, for
Chip fp7192 constant pressure chips, its steady-state value are 0.6v), so K is necessarily a fixed value, so formula：
Io=K/R5 has the fabulous linearity, and has excellent controllability.
Parameter above being assigned the occurrence being set above can obtain：
Io=(VFB* (R1+R2)-R2*VREF+)/R1*R5
=(0.6* (40+10) -10*2.5)/40*0.1
=1.25A
It can be seen that, this scheme introduces fixed VREF+ in equation more than, is only taken so that Io becomes one with R5
The linear equation of sample resistance, makes Io become constant, so as to reach the purpose of constant current.
The characteristics of constant-current circuit in this programme, is as follows：
1. use stable control and the stability control fixed VREF+ voltages, be easy to precision.
Fed back 2. current sample is become electric resistance partial pressure by use, it is more simple and reliable.
3. applicability is wide, the circuit of any required constant current can use.
Cost is greatly reduced, and cost is to use the 1/3 of IC constant current schemes.
