It has been confirmed that a typical IC sample does not break down even if pins are short-circuitted for one second. It has been confirmed that a typical IC sample does not emitting smoke and fire even if pins are short-circuitted for ten seconds. This is not inspected for all ICs. The mark x shows that a breakdown may be caused if the pins are short-circuitted. Full care must be taken on using the IC. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 Pin No. q q q q q q q q q q q q q q q 1 q q q q x q q q q q q q q x 2 q q q q q q q q q q q q q 3 q q q q q q q q q q q q 4 q q q q q q q q q q q 5 q q q q q q q q q q 6 q q x q q q q q q 7 q q q q q q q q 8 q q q q q q q 9 q q q q q x 10 q q q q q 11 q q q q 12 q q q 13 q q 14 q 15 16 7 AN5757S s Application Circuit Example ICs for TV 12 V 10 k B 2.7 k 1.82 k 68 k +B 0.047 F 0.1 F 75 k 16 15 14 13 12 11 10 DTC VCC2 GND2 Sync. in Duty adjustment Ramp generator 1 2 3 4 5 6 7 P-ch. 33 nF To +B PWM output HD input Note) When both of the pin 4 and the pin 5 are open, minimum pulse width of PWM output is 2.0 s. 8 5 k 5V 0V 50 pF 10 k 33 8 190 V 9 47 F Request for your special attention and precautions in using the technical information and semiconductors described in this material (1) An export permit needs to be obtained from the competent authorities of the Japanese Government if any of the products or technologies described in this material and controlled under the "Foreign Exchange and Foreign Trade Law" is to be exported or taken out of Japan.
