Abstract: Various aspects can be implemented to achieve efficient voltage conversion. In general, one aspect can be a switching regulator for DC-DC step-down voltage conversion that includes a high-side transistor and a low-side transistor coupled in series and a first circuitry configured to operate in a synchronous mode such that the high-side transistor and the low-side transistor are used for voltage switching. The switching regulator also includes a second circuitry configured to operate in a non-synchronous mode such that the high-side transistor and one or more diodes are used for voltage switching. The switching regulator further includes an automatic mode selector configured to output a control signal and automatically select between the synchronous mode of operation and the non-synchronous mode synchronous mode of operation based in part on a voltage between source and drain of the low-side transistor and a predetermined delay time.

Abstract: A wiping device for an inkjet printer includes a wiper mount moveable between a wiping position and a non-wiping position. A slider coupled to the wiper mount, translates between a retracted position and a deployed position. A first translation of the slider to the deployed position causes the wiper mount to move into the wiping position. A trigger, operable between a cocked position and an un-cocked position is coupled to the slider. In the cocked position, the trigger locks the wiper mount in the wiping position. When actuated, the trigger moves to the un-cocked position and the wiper mount moves to the non-wiping position. The wiping device includes logic to control the actuation and non-actuation of trigger.

Abstract: A switch state controller generating a pulse train is used in a power converter utilizing a plurality of converter stages all simultaneously controlled by a single switch controlled by said pulse train. On time of the pulse train is controlled according to an input or interim node characteristic of the supply and period is controlled by a characteristic of the output of the converter. This allows development of AC-to-DC converters, including power-factor-correction converters, and DC to DC converters with high conversion ratio with minimal parts count & high reliability.

Abstract: A switching power converter and method of controlling an output voltage thereof using predictive sensing of magnetic flux provides a low-cost switching power converter via primary-side control using a primary-side winding. An integrator generates a voltage that represents flux within a magnetic element by integrating a primary-side winding voltage. A detection circuit detects the end of a half-cycle of post-conduction resonance that occurs in the power magnetic element subsequent to zero energy level in the power magnetic element. The integrator voltage is stored at the end of the half-cycle and is used to determine a sampling point prior to or equal to the start of post-conduction resonance in a subsequent switching cycle of the power converter. The primary-side winding voltage is then sampled at the sampling point, providing an indication of the output voltage of the power converter by which the output voltage of the converter can be controlled.

Abstract: An apparatus and method for adaptively controlling power supplied to a hot-pluggable subsystem controls the inrush current of the hot-pluggable subsystem when the subsystem is coupled to another system that supplies power, and optionally other signal connections. The apparatus and method adaptively control a pass device by detecting the voltage at the gate of the pass device during initial charging of the gate. The gate voltage may be sampled and used subsequently to control the operation of the pass device, and short-circuit conditions may be detected by determining that the miller effect does not change the charging of the gate capacitance. Automatic restart circuitry can be included to generate multiple startup attempts, and under-voltage lockout circuitry and power-on-reset timers can be used to provide a robust solution. The apparatus and method can be adapted to provide a three terminal device that does not require a feedback connection from a power supply output. The three terminal device may include the pass device, or may control an external pass device.

Abstract: A feedback apparatus and method for adaptively controlling power supplied to a hot-pluggable subsystem controls the inrush current of the hot-pluggable subsystem upon application of power. The apparatus and method adaptively control a pass device by detecting the current through the pass device during initial charging of a load capacitance and scaling back the turn-on rate at the pass device control terminal input in conformity with the detected current and a predetermined rate set by a ramp generator. A ramp capacitor is coupled to the control terminal of the pass device through a diode to permit use of the capacitor for timing purposes as well as preventing transient turn-on of the pass device during initial application of power.
