Latest Patents

Cheng's latest patents include a multi-phase switching regulator and driver circuit, along with a control method for the same. This invention discloses a multi-phase switching regulator that consists of at least two power stages. The switching power transistors in these stages convert an input voltage to an output voltage based on pulse width modulation (PWM) signals generated by corresponding PWM controllers. Additionally, a current balance circuit generates a current balance signal to evenly distribute current across the active power stages. This design allows for adjustable gain in the current balance circuit, which helps to minimize output voltage overshoot and undershoot during phase number changes.

Another significant patent by Cheng is related to a control circuit and method for a fly-back voltage converter. This invention includes a transformer that transforms primary current to secondary current, with a switch that is serially coupled to the primary winding. The control method involves producing a detection signal by comparing the secondary current with two threshold values, which triggers the next on-time cycle of the switch. The hysteresis range of the threshold values is designed to prevent error detection of the secondary current.
