Working Principle

The MC33167TG allows application designers to realize a robust and efficient step-down voltage conversion solution. It utilizes a quasi-constant frequency current-mode pulse width modulation (PWM) control scheme which provides a good noise performance and fast switching speed. The device can achieve up to 92% efficiency.The MC33167TG control logic block consists of an error amplifier, approximately two voltage reference PWM logic and error amplifier output logic. The error amplifier monitors the output voltage and provides feedback to keep it stable. The PWM logic controls the frequency of the Pulse Width Modulated (PWM) signal that is sent to the output switches. When the error amplifier detects an output voltage error, the PWM logic adjusts the pulse width to correct it. The MC33167TG also contains an adjustable output voltage regulator, which can be adjusted from 0.6V to 5.5V using an external resistor divider. This feature makes the device suitable for a variety of applications where an adjustable output voltage is required.
