  • Publication number: 20230275509
    Abstract: A DC-DC converter includes a ramp generator, a threshold voltage circuit, and a control circuit. The ramp generator is configured to generate a voltage ramp. The threshold voltage circuit is configured to generate a threshold voltage. The control circuit is coupled to the ramp generator and the threshold voltage circuit. The control circuit includes a digital pulse width modulator (DPWM) circuit and a loop compensation circuit coupled to the DPWM circuit. The DPWM circuit is configured to generate a power stage switch control signal responsive to a loop compensation value. The loop compensation circuit is coupled to the DPWM circuit. The loop compensation circuit is configured to calculate the loop compensation value responsive to the voltage ramp exceeding the threshold voltage.

  • Publication number: 20110211370
    Abstract: Systems and methods of resonant DC/DC conversion disclosed herein improve the basic resonant converter designs by proactively setting and coordinating the gate drive timings between the primary side and secondary side. By proactively setting and coordinating gate drives timings between the primary side and secondary side, both efficiency and transient performance optimizations may be achieved with or without diode emulation mode, depending on whether the switching frequency is below resonance or above resonance, and the nature of the load characteristics. If the switching frequency of the converter is determined to be at or below the resonance frequency, the output transistors may be configured to be fully active at or above a predetermined output load current. The turn-on timing of the output transistors is dependant on the load for a given output voltage, and is almost independent of input voltage. Turn-on timing may be significantly different at light load to no load.

  • Patent number: 6192430
    Abstract: A mixed-signal processor (MSP) chip with a flexible serial interface which simultaneously accommodates two serial ports on a reduced number of pins. The pin definitions of these serial ports are configured to function well with several different external chips. Any two of these chips, or two of any one of these chips, may be used concurrently by the present MSP. When used with chips that require it, the present MSP chip provides a clock signal to each of these. When used with other chips, the MSP will can receive a clock signal from an external chip, and will then pass this signal through to any chip on the other of the two serial ports.
