Application Fields

The PT6627D DC-DC converter is especially suitable for applications in medium/large-scale DC power systems. The output current is limited to 66 A/channel, making it ideal for intermediate bus applications where high-current conversion is required. It can also be used in industrial and medical applications, automotive systems, and telecom power systems, and is suitable for applications operating from a wide (4.5 - 48 V) input voltage range.

Due to its high efficiency, 95% under light load, the PT6627D DC-DC converter is a great choice for applications that need to conserve power in addition to delivering high-current output. The low quiescent current helps reduce system power losses when in standby mode, making the converter ideal for applications such as cooling fan control and various monitoring applications.

Working Principle

The PT6627D converter is an isolated dual DC/DC converter with two independent step-down output channels. The high-efficiency and low-ripple approach is achieved by using advanced secondary synchronous rectification and peak current mode control architecture. The input voltage is rectified and controlled by an internal power switch operating in continuous conduction mode (CCM) to minimize the output ripple.

The fixed frequency pulse width modulation (PWM) controller with its internal compensation provides accurate output regulation and allows the users to adjust the output voltage, via an external resistor divider. The PT6627D features automatic pulse-frequency modulation (PFM) mode changing to maintain highest efficiency in light load conditions. The soft-start feature and the over current and short circuit protection enables the device to handle even the most challenging load conditions.

Conclusion

The PT6627D DC/DC converter from PowerTips™ technology offers high efficiency and advanced power management features, making it ideal for a variety of industrial, computing, telecommunications and residential applications. With a wide 4.5 V to 48 V input voltage range, tight output voltage accuracy, 95% efficiency in light load applications, and a small footprint, the PT6627D provides an ideal solution for intermediate bus and point-of-load applications.
