5. Feedback control circuit

Fig. 2-17

- F/B terminal of PIC1 determines output duty cycle.
- Duty definition : Refer to Vs1 in Fig4-10.(Duty up: Vs1 up, Duty down: Vs2 down)
- C-E(Collector-Emitter) of PIC2 and F/B potential of PIC1 are same.
- At F/B terminal open : SHUT OFF mode

È

F/B potential is set to 3.6V internally.

F/B potential decreases to 1-2V by C-E voltage of PIC2 ( controlled by normal
operation. )

È

When F/B terminal is open, shut off occurs because 2.8V is exceeded.

(Refer to clause 4.)

Operation descriptions

a. Internal OP-Amp Ô+Õ base potential of PIC3 is 2.5V and external Ò-Ó input potential is connected with PR38

and PR39 to maintain Vout of 5.8V. (Vout = ((PR36 x PR39) / PR39) x 2.5V)

b. If load of 5.8 V terminal increases(or AC input voltage decreases) and Vout decreases below 5.8V, then :

PIC3 ÔPÕ potential down below 2.5V

-->

PIC3 A-K of base current down

-->

Maintain 5.8V

(i.e., the feedback to maintains 5.8V).
- PR35, PR36 : Reduce 5.8V overshoot
- PR37, PC43 : Prevent IC3 oscillation(for phase correction)
- PC18 : Adjust feedback response rate
