摘要： A complementary output generator (COG) module generates at least two complementary outputs determined by rising and falling event sources. In a simple configuration of the COG module, the rising and falling event sources are the same signal which is a signal having the desired period and duty cycle. The COG module converts this single signal input into dual complementary outputs. The frequency and duty cycle of the dual outputs substantially match those of the single input signal. Blanking and deadband times may be introduced between the complementary outputs, and the dual complementary outputs may also be phase delayed. In addition the COG module may provide up to four outputs for controlling half and full-wave bridge power applications.

摘要： A slope compensation module provides slope compensation of a switched-mode power supply using current mode control. The slope control unit comprises a capacitor coupled between an input and an output of the slope control unit, a switch for discharging the capacitor and a constant current source for charging the capacitor. Slope compensation parameters may be changed during operation with a programmable constant current source. The slope compensation module may also function as an analog sawtooth waveform frequency generator, and as an analog pulse width modulation (PWM) generator. Charging the capacitor generates a linearly decreasing (negative slope) ramp voltage for modulating a feedback error voltage into a slope compensated feedback error voltage. Capacitor charging may be controlled from a pulse width modulation signal. Opening of the switch may be programmably delayed, and a minimum closed time thereof may also be programmed during operation of the slope compensation module.
