Width Modulator
The PT3995 is a Pulse Width Modulation (PWM) integrated circuit manufactured by Pacific Timer Corporation. It is used in a variety of applications including motor speed control, LED illumination control, and audio power control. The IC includes an internal oscillator, allowing the user to set the PWM frequency without the need for an external oscillator. In addition, the IC features adjustable PWM duty cycle, adjustable PWM dead-time and a wide LED current range. It is available in a small QFN8 package, and can operate over a wide voltage range of 2.7V to 5.5V.
