Tl494 Pwm Adjustable Pulse Generator Module

Description:

This generator module, based on the TL494 chipset is able to generate a 5V PWM signal between 500Hz-100kHz. The frequency and duty cycle are adjustable to allow for easy tuning. This makes it ideal as a consistent trigger for other devices, such as interval based sensor reading.

Specification:

• Working voltage: DC 7V-40V
• Operating frequency 500Hz-100kHz (adjustable R6)
• Maximum output current: 250mA
• Output voltage: DC 5V
• Complete PWM power-control circuitry
• Uncommitted Outputs for 200-mA Sink or source current
• Output control selects single-ended or push-pull operation
• Internal circuitry prohibits double pulse at either output
• Variable dead time provides control over the total range
• The internal regulator provides a stable 5-V reference supply with 5% tolerance
• Circuit architecture allows easy synchronization
• Working voltage: DC 7V-40V
• Operating frequency 500Hz-100kHz (adjustable R6)
