DC DC Converters - PT6651L application field and working principle

A DC DC converter is an electronic device that works as an energy transformation device by converting direct current (DC) from a battery or other direct current source into a different DC voltage. The PT6651L is a DC DC converter that integrated a topology of constant current source-BCM (Buck-Boost-Compensated Modulator).

Application Field

The PT6651L is currently used in various long line, low power applications, such as LED lighting, security monitoring, data communication, industrial control, consumer electronics, point-of-sale equipment, medical equipment, and automotive electronics.

Working Principle

The PT6651L is a DC power converter with a constant current source BCM (Buck- Boost-Compensated Modulator) topology. Its main component is a PMOS switch (p-channel MOSFET) with dynamic linear regulation, which works as a primary switch to adjust the output current and voltage. Additional, the output inductor is used to reduce power disruptions and EMI problems.

In the PT6651L, the PMOS switch is driven by a fixed switching frequency. As the voltage input changes, the control circuit will adjust the switch duty cycle to maintain a constant current source. The constant current source will be applied to the output inductor, which in turn will adjust the output voltage as the input voltage changes. Therefore, the PT6651L can transform the input voltage into any desired output voltage and current while maintaining a constant current source.

In addition, the PT6651L can adjust the output voltage from 0.6V to 5.5V, with the maximum output power of 2.5W. It adopts 8-pin SOP format, which is compatible with current applications. All in all, the PT6651L is an ideal choice for long-line applications that require low power conversion.

Conclusion

The PT6651L is a DC DC converter that adopts a constant current source topology to maintain a constant current source and convert the input voltage into any desired output voltage and current. It is used in various long line, low power applications, such as LED lighting, security monitoring, data communication, industrial control, consumer electronics, point-of-sale equipment, medical equipment, and automotive electronics.
