PT6621G Application Field

The PT6621G can be used in a variety of applications, including for the powering of portable electronic products, such as cellphones, laptops, etc. This converter is also suitable for voltage conversion in on-board electronic systems, such as multi-voltage systems, battery charger modules, automotive systems, etc. In addition, it can be used in test and measurement, or other applications utilizing bidirectional voltage conversion.

PT6621G Working Principle

The PT6621G operates by using high-frequency pulse width modulation (PWM) to convert dc power from one voltage level to another. The device is controlled by an internal microcontroller which controls the duty cycle of the PWM signal. PWM is a type of power conversion technology that offers higher efficiency and power density than simpler linear voltage regulators. It works by rapidly switching a power supply on and off, sending pulses of current to the load, which is then averaged out to the desired output voltage. By carefully controlling the pulse width and frequency, the output voltage from the converter can be accurately controlled.

The PT6621G also features a wide range of input voltages, from 6V to 40V, making it suitable for a variety of different applications. It is capable of providing output voltages between 0.8V and 36V, allowing for a broad range of voltage conversion ratios. In addition, the converter is capable of delivering up to 300W of power with a maximum efficiency of 95.5%, making it one of the most efficient DC-DC converters on the market today.

Conclusion

The PT6621G is a highly efficient and versatile DC-DC converter available on the market. Its wide range of input and output voltage options make it suitable for a variety of applications, including the powering of portable electronic products, or for on-board electronic systems. The device operates by utilizing PWM to convert energy from a higher voltage source to a lower voltage source, and vice-versa, allowing for accurate control of output voltage. With its high power density and efficiency, the PT6621G is an ideal choice for any application requiring the conversion of dc power.
