In 1972, Signetics originally released the 555 timer in DIP-8 and TO5-8 metal can packages, and the 556 timer was released in a DIP-14 package. [ 4 ] In 2006, the dual 556 timer was available in through-hole packages as DIP-14 (2.54 mm pitch), [ 21 ] and surface-mount packages as SO-14 (1.27 mm pitch) and SSOP-14 (0.65 mm pitch).

PWM is useful for controlling the average power or amplitude delivered by an electrical signal. The average value of voltage (and current) fed to the load is controlled by switching the supply between 0 and 100% at a rate faster than it takes the load to change significantly. The longer the switch is on, the higher the total power supplied to ...
Signetics Corporation was an American electronics manufacturer specifically established to make integrated circuits. [1] Founded in 1961, they went on to develop a number of early microprocessors and support chips, as well as the widely used 555 timer chip.

PWM is considered the most common deterministic technique. Considering the example of a DC-DC converter, a controlled switch is designed to “cut-off” the DC waveform into a pulse-shaped waveform. Therefore, the voltage of this signal alternates at the switching frequency between a maximum value and zero.
