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 |
