MC33060A - PULSE WIDTH MODULATOR CONTROLLER

This page provides the datasheet information for the MC33060A, a member of the MC34060A PULSE WIDTH MODULATOR CONTROLLER family.

Description

The MC34060A is a fixed

frequency pulse width modulation control circuit, incorporating the primary building blocks required for the control of a switching power supply (see Figure 1).

linear sawtooth oscillator is frequency programmable by two external components

Features

  • ead time.
  • control input to a fixed voltage, ranging between 0 V to 3.3 V. The pulse width modulator comparator provides a means for the error amplifiers to adjust the output pulse width from the maximum percent on.
  • time, established by the dead time control input, down to zero, as the voltage at the feedback pin.
