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 × 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. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 7 AN5757S ICs for TV ■ Application Circuit Example +B 10 9 7 8 11 12 13 14 15 16 75 kΩ DTC VCC2 P-ch. 33 nF PWM output 6 5 4 3 5V 0V 5 kΩ 10 kΩ 33 Ω 2 1 190 V Ramp generator Duty adjustment Sync. in 50 pF GND2 HD input To +B Note) When both of the pin 4 and the pin 5 are open, minimum pulse width of PWM output is 2.0 µs. 8 47 µF 0.1 µF 2.7 kΩ 10 kΩ B 0.047 µF 1.82 kΩ 68 kΩ 12 V
