NE555 PWM signal output module -generator duty cycle adjustable frequency 10 kHz | Обустройство дома

[Brief description] Size: 45 mm long * 24 mm wide * 25 mm high II. Main chips: NE555 3. Working Voltage: DC 4-16V 4. Working current: less than 10 mA 5. Maximum output current: 225 mA 6. Output Frequency 10Khz (Frequency can be changed by changing capacitance) 7. The duty cycle of output is adjustable from 0% to 100%. [Relevant knowledge] General situation of PWM PWM is the abbreviation of pulse width modulation. The ratio of square wave high level time to period is called duty cycle. For example, the duty cycle of 1 second high level 1 second low level PWM wave is 50%. Interpretation of Pulse Width Modulation PWM Pulse width modulation (PWM) is a term used in switching regulated power supply. This is classified according to the control mode of voltage stabilization, besides PWM type, there are also PFM type, PWM, PFM hybrid type. Pulse Width Modulation (PWM) switching regulator circuit is to stabilize the output voltage by adjusting its duty cycle through voltage feedback when the output frequency of the control circuit is constant. Pulse Width Modulation PWM Life Extension Pulse width modulation (PWM) is a very effective technology to control analog circuits by using digital output of microprocessors. It is widely used in many fields, from measurement, communication to power control and conversion. [Annotation Notes]
