摘要： A DC-DC converter operating in pulse frequency modulation (PFM) and pulse width modulation (PWM) modes includes a plurality of PWM signal generators. The PWM signal generators generate PWM signals with different duty cycles. PWM signals with larger duty cycles may be selected for use in undervoltage situations.

摘要： A timing controller (C1) in an inverter, an inverter controller (C30), and a plurality of converter controllers (C21 to C26) are connected via a communication line (L2). The timing controller (C1) is configured to provide timing signals to the respective inverter controller (C30) and converter controllers (C21 to C26) in predetermined time cycles which have been set in advance. The respective timing signals are provided so as to prevent two or more of the inverter (30) and converters (21 to 26) from starting to be driven at the same time.

摘要： A control circuit for use in a power converter in one aspect limits the magnetic flux in a transformer of a switching power converter. A first controlled current source has a first current that is substantially directly proportional to an input voltage to be applied to a winding of the transformer. A second controlled current source has a second current that is substantially directly proportional to a reset voltage to be applied to the winding of the transformer. A first switch is adapted to charge an integrating capacitor with the first current while the input voltage is applied to the winding of the transformer. A second switch is adapted to discharge the integrating capacitor with the second current when the reset voltage is applied to the winding of the transformer. A third switch is adapted to remove and to prevent application of the input voltage to the winding of the transformer.

摘要： A voltage supply circuit (
1 ) is provided. The voltage supply circuit may operate at a first or second mode to generate an output voltage (
VOUT ) at an output node (
NOUT ). The voltage supply circuit includes a compensation circuit (
10 ), a comparator circuit (
11 ), an inductor (
13 ), and a driver circuit (
12 ). The compensation circuit generates a compensation signal (
S10 ) according to a feedback signal (
SFB ) related to the output voltage. The comparator circuit compares the compensation signal with a first reference signal (
SRAMP ) to generate a comparison signal (
S11 ). The inductor is coupled to the output node. The driver circuit receives the comparison signal and generates a driving voltage (
V12 ) to the inductor according to the comparison signal. When the voltage supply circuit enters the second mode from the first mode, a duty of the comparison signal is increased to broaden an operation bandwidth of the voltage supply circuit in a predetermined period at the second mode.

摘要： A data storage device (DSD) includes a power supply from a host and a charge storage element. A current transient is detected on the power supply from the host and it is determined whether the current transient exceeds a current threshold. When the current transient exceeds the current threshold, power is drawn from the charge storage element to reduce power drawn from the host.

摘要： A variable efficiency and response buck converter is achieved. The device includes a multi-phase switch, the coupled coils, the filter capacitor, and the load. The multi-phase switch includes the phase control inputs, the circuit common reference, at least two pairs of complementary switches with each switch containing one upper switch and one lower switch, at least two phase control outputs from the complementary switches. The coupled inductive coils are coupled to the phase control outputs to enable weak couplings and strong couplings. Based on the working mode, equivalently the coupled coils can provide strong mutual inductances and weak mutual inductances. The filter capacitors connected to the output of the coupled coils provide high efficiency output to the load.
