PT4244N

The PT4244N is a member of the DC DC Converters group. Its use and applications are widespread throughout the industry, from consumer electronics to industrial products. This article looks at the roles PT4244N plays in the industry and explains the working principles to its use.

Application Field

PT4244N is one kind of the DC-DC converter devices that can be used to change the DC voltage from a high level to a lower level. It is very efficient and widely used in portable electronic equipment such as Tablet/Laptop computers, cell phones, digital cameras, Audio players and more. The maximum input voltage range is from 3.4V to 32V, while the maximum output voltage range is from 0.5V to 26V. The maximum output current is 2A, and it integrates the switching MOSFET, the best feature of this product is that it is extremely low input current, so no external standby power is required. At the same time, it is designed in high-efficiency, high-power-density and high-power-transmission applications. PT4244N, with its wide input voltage and low input current, is the ideal choice for battery powered applications. Most notably, it is adopted in the latest telecommunications and mobile device applications to help optimize power usage, heat dissipation and reliability.

Working Principle

The PT4244N adopts the step-down DC-DC conversion technology. Its operating principle can be divided into two parts. The primary part is performing the step-down conversion with the help of a switch element. When the switch is off, the energy stored in the inductor will flow to the output, and when the switch is on, the input voltage is converted to the output voltage accordingly. The secondary part of the working principle is an automatic control circuit, which is used to control the switch on and off. The switching speed of the PT4244N is adjustable from 1Khz to 1Mhz, which gives the customers more options to design electronic products. It also contains a voltage limit circuit, current limit circuit, thermal shut down circuit and other safety protection functions. When the input voltage is lower than the set and required output voltage value, it will automatically stop working to ensure the safety of the device

In conclusion, the PT4244N is very effective and is one of the most sought-after products of the DC DC converters family. Its ability to convert DC voltages at high efficiency and with very low power consumption, makes it a preferred choice for many applications. Its wide input voltage, adjustable switching speed and integrated switching MOSFET make it the perfect solution for any battery powered applications.
