Biomolecule transfer device

In some embodiments, upon detecting a fault condition, switching in a switched mode power supply is disabled only after a current switching cycle of the switched mode power supply is completed.

Switched mode power supply controller

In an example, a controller device for a resonant converter includes processing circuitry configured to output a first switching signal and a second switching signal. A switching module is configured to electrically couple a primary side winding of a transformer to a voltage source during an activated state of the first switching signal and to electrically couple the primary side winding to a reference node during an activated state of the second switching signal. The processing circuitry is further configured to determine a first synchronous rectification signal and a second synchronous rectification signal. A synchronous rectification module is configured to generate a first channel for a first secondary side winding of the transformer during an activated state of the first synchronous rectification signal and to generate a second channel for a second secondary side winding of the transformer during an activated state of the second synchronous rectification signal.

Controller device with adaptive synchronous rectification

A device for current protection comprises a switch-mode power supply controller. The switch-mode power supply controller includes an inrush current comparator that is arranged to compare a primary winding current with an inrush current threshold at least during at least one of a startup phase or a burst phase. The switch-mode power supply controller also includes a switch controller that is arranged to control regulation of an output voltage by controlling turning of a primary switch on and off based on a feedback signal that is based, at least in part, on the output voltage. The switch controller is further arranged to, if the inrush current comparator determines that the primary winding current has reached the inrush current threshold, control the primary switch to turn off and remain turned off until at least a next switching cycle.
