We don't know because we don't make mobile phones.pls, tell the name of led which are used in mobile phones.
Ask a mobile phone manufacturer like Nokia.

The duty cycle is the ratio of the two resistors since both resistors charge the timing capacitor and only one of the resistors discharges the capacitor.what is duty cycle in 555 Ic ??
Sir where it is used and why diode are used??The duty cycle is the ratio of the two resistors since both resistors charge the timing capacitor and only one of the resistors discharges the capacitor.
It cannot reach 50:50 or more unless two diodes are added then a pot can make any duty cycle you want.
pls, explain the use of diode in brief.Here is a 555 PWM circuit with a duty-cycle from about 3% to about 97%:
Each diode conducts when its has a forward bias voltage across it.pls, explain the use of diode in brief.
Of course it is different, it has an adjustable duty-cycle.But the o/p is taken from pin 3, and this circuit is really different from simple 555 ic ckt.
