    Abstract: A wall control interface for power management includes a transmitting circuit that generates a switching signal to control a switch and achieve a phase modulation to a power line signal in response to a transmitting-data. A receiving circuit is coupled to detect the phase of the power line signal for generating a data signal and a receiving-data in response to the phase of the power line signal. The receiving circuit further generates a control signal to control power of a load in accordance with the data signal or the receiving-data. The phase modulation is achieved by controlling a turn-on angle of the power line signal. The switch remains in a turn-on state during the normal condition, which achieves good power and low current harmonic. The phase modulation is only performed during the communication of the power management.

    Abstract: The present invention provides a primary-side flyback power converter that supplies a constant voltage output and a constant current output. To generate a well-regulated output voltage under varying load conditions, a PWM controller is included in the power converter in order to generate a PWM signal controlling a switching transistor in response to a flyback voltage sampled from a first primary winding of the power supply transformer. Several improvements are included in this present invention to overcome the disadvantages of prior-art flyback power converters. Firstly, the flyback energy of the first primary winding is used as a DC power source for the PWM controller in order to reduce power consumption. A double sample amplifier samples the flyback voltage just before the transformer current drops to zero. Moreover, an offset current is pulled from a detection input of the double sample amplifier in order to generate a more accurate DC output voltage. The offset current is generated in response to the temperature in order to compensate for temperature-induced voltage fluctuations across the output rectifier. Ultimately, in order to maintain a constant output current, the PWM controller modulates the switching frequency in response to the output voltage.

    Abstract: A method and apparatus to dynamically modify internal compensation of a low dropout (LDO) voltage regulator is provided. The LDO voltage regulator includes an output pass transistor, an error amplifier, a bias transistor and a compensation network. The compensation network is connected between a gate and a drain of the output pass transistor to compensate for the feedback loop. The compensation network and the bias transistor generate pole-zero pairs to perform a maximum 45 degrees phase shift before reaching the crossover frequency in the LDO voltage regulator. Therefore a minimum 45 degrees phase margin is provided for the feedback loop in various load conditions. Furthermore, the pole-zero pairs produced in the LDO voltage regulator are adaptively adjusted according to load conditions, so that the bandwidth is optimized and faster transient response is achieved.

    Abstract: A high voltage LDMOS transistor according to the present invention includes a P-field and divided P-fields in an extended drain region of a N-well. The P-field and divided P-fields form junction-fields in the N-well, in which a drift region is fully depleted before breakdown occurs. Therefore, a higher breakdown voltage is achieved and a higher doping density of the N-well is allowed. Higher doping density can effectively reduce the on-resistance of the LDMOS transistor. Furthermore, the N-well generated beneath a source diffusion region provides a low-impedance path for a source region, which restrict the transistor current flow in between a drain region and a source region.

    Abstract: A high voltage LDMOS transistor according to the present invention includes P-field blocks in the extended drain region of a N-well. The P-field blocks form the junction-fields in the N-well for equalizing the capacitance of parasitic capacitors between the drain region and the source region and fully deplete the drift region before breakdown occurs. A higher breakdown voltage is therefore achieved and the N-well having a higher doping density is thus allowed. The higher doping density reduces the on-resistance of the transistor. Furthermore, the portion of the N-well generated beneath the source diffusion region produces a low-impedance path for the source region, which restricts the transistor current flow in between the drain region and the source region.

The PWM controller generates a PWM signal to control a switching transistor in response to a flyback voltage detected from the first primary winding of the power supply transformer.
