• Appliances such as washing machines and microwaves
• Automotive chargers

The PT4661N is a reliable, low-cost solution which has been used by many major companies worldwide, such as Nokia, Hyundai and Samsung.

PT4661N Working Principles

The PT4661N is a monolithic DC-DC switching converter powered by a single low voltage source. It integrates a driver, a power MOSFET and various protection circuits into a single chip. This IC is able to convert a voltage range of 1.8V to 5.5V to a higher value. It is also able to support a continuous operation with up to 5A maximum current.

The PT4661N\'s operating principle is based on a Pulse Width Modulation (PWM) control system. The input voltage is first compared with the set point voltage (Vref) set by the user. A Pulse Width Modulated (PWM) square wave signal is then generated to control the power MOSFET switch on/off. When turned on, the switch connects the input voltage to the output. The output voltage is then filtered before being sent back to the output terminal. The whole process will be repeated 100,000 times per second, to ensure the stability and efficiency of the power supply.

The PT4661N is a versatile DC-DC converter which can be used to power a wide range of consumer, medical and industrial applications. The PWM control system and intelligent protection circuits also add to its overall reliability and safety.

Conclusion

The PT4661N is a very useful DC-DC converter which has been used in many areas such as consumer electronics, automotive, medical and industrial applications. Its low cost and reliable performance make it an ideal choice for high power applications. It\'s built in protection features also make it a safe choice With all its advanced features, the PT4661N is a great option for anyone looking for an efficient DC-DC converter.
