Abstract: A multi-phase DC-to-DC converter is configured to achieve fast transient response and to optimize efficiency over the load range. Phase shedding changes the active number of phases according to output currents. Each phase of the converter has an inductor configured to optimize the efficiency for a range of load currents in which that phase is used. A converter may have 3 phases, the first used only in sleep mode and has a large inductance with low AC losses, the second used in sync mode at low currents and having a lower inductance with low AC losses, the third phase is used in sync mode at high currents and has small inductance with low DC losses. The number of phases is ≧2.

Abstract: A dual mode low dropout voltage regulator has a low dropout regulation mode and a bypass mode and provides a smooth transition between mode transitions taking place under load. When an accessory requires a larger voltage level, a bypass signal commands the dual mode low dropout voltage regulator to go into bypass mode and transfer voltage level of the unregulated input voltage source to the output of the dual mode low dropout voltage regulator. The dual mode low dropout voltage regulator provides a smooth transition to the bypass to prevent the output of the dual mode low dropout voltage regulator from decreasing or having a “brown out” until a pass transistor is forced to turn on fully to provide the voltage level of the unregulated input voltage source to fully bypass the low dropout regulating mode of operation.

Abstract: Methods and circuits for CMOS relaxation oscillators are disclosed. A single capacitive element, a single current source and a switching network are utilized. A switching network of the oscillator allows both nodes of the capacitive element to rise and fall between a positive and a negative voltage with respect to ground supply, without causing leakage to substrate or risk of latch-up, i.e. the inadvertent creation of a low-impedance path. The oscillator requires minimum silicon area, has an improved duty cycle, is particular useful for implementing lower frequency clocks and is enabled for smaller technology nodes, lower than 250 nm, due to lower supply voltage.

Abstract: In order to control of dimming of solid state lighting devices (SSL) a driver circuit drives the SSL subject to an input voltage using a phase-cut dimmer. The driver circuit comprises a transistor operable in two modes, either alternating between on/off states or continuously controlling a current through the transistor. A power converter network provides a switched-mode power converter in conjunction with the transistor when operated in the first mode generating a drive voltage for the SSL. The control unit controls the transistor to selectively operate in one of the two modes; to control the transistor to determine that the input voltage exceeds an input voltage threshold; and to control a drive current through the SSL based on a measurement of a phase-cut angle thereby controlling an illumination level of the SSL device.
