Latest Patents

Sivaraj's latest patents include a multi-mode transition for a DC-DC converter. This invention discloses embodiments of a multi-mode transition circuit that includes a transconductance amplifier connected to a resistor-capacitor (RC) network and switches. Additionally, it features a comparator connected to a second RC network, with both networks linked to a reference voltage. The operation mode selector in this invention enables or disables the transconductance amplifier and controls the switches during transitions between pulse-frequency modulation (PFM) and pulse-width modulation (PWM) modes.

Another significant patent is the open-circuit detector. This invention comprises a first current source that injects current at the output of a closed-loop circuit. The detector monitors the voltage of the closed-loop circuit and indicates whether the monitored voltage exceeds a predetermined threshold. The controller regulates the current injected by the first current source and sets an open-circuit flag if the current causes the voltage to exceed the threshold.
