DC DC Converters

The QPW060A0M1-HZ DC/DC converter is a migration product from PMBus to PMBus Plus, providing a satisfying experience for users who need the industry-standard command set and superb performance. It is applicable for various kinds of applications, such as computers, mobile phones, tablets, communications, industrial control, instrumentation and medical equipment.

Application Field

The application fields of the QPW060A0M1-HZ cover various aspects. It can be a step-down/step-up or a separated converter, and it can also work as a controller for single-phase low power or multi-phase high power for power conversion. It is usually used in mobile phones, tablets, laptops, computers, communications, industrial control, instrumentation, medical equipment, as well as renewable energy.

Working Principle

The QPW060A0M1-HZ works according to the constant current-mode control principle. It exchanges power and energy in either step-up or step-down configuration, taking power from one or more sources on one side and output to a load on the other side.

The main parts of the circuit include the MOSFETs, a pulse width modulation (PWM) controller, an inductor, a capacitor and an auxiliary winding circuit. The PWM controller will generate a pulses and induce a voltage from the transformer\'s auxiliary winding which will help to latch the MOSFETs and change the waveforms and power conversion ratio. The process is then repeated and the output voltage can be selected by adjusting the duty cycle of the PWM controller.

The advanced PMBus command set not only ensures the ease-to-develop feature, but also the power saving function. The power management control system makes sure that the DC-DC converter is only in operation when power is needed, which means it will monitor and respond to the run-time variations of the power management needs. Therefore, the power usage can be kept at an optimal level and the power efficiency is greatly improved.

Conclusion

The QPW060A0M1-HZ DC/DC converter is a powerful and efficient DC/DC converter, with advanced PMBus command set and powerful performance. It is applicable for scalability, high power conversions and can be used in a wide range of applications, such as computer, communication, industrial control, instrumentation and medical fields.
