What output configurations are available with PWM controllers?
PWM controllers may have single-ended or dual outputs. Dual output types are intended for either for push-pull, bridge or synchronous rectifier MOSFETs. In these configurations the PWM controller must either accurately set the two outputs dead time or prevent their overlap. If both outputs were allowed to be ON simultaneously it would increase power dissipation and EMI. Some PWM controllers include special circuits to control dead time or overlap.
