DC-DC converters are devices that can convert a DC power supply into one or more DC outputs. This conversion is usually accomplished with the use of inductors, capacitors and switches. PT4243N is one type of DC-DC converter which provides a high-efficiency, cost-effective means for supplying multiple outputs.PT4243N is a high-current DC-DC converter from Power Trends that utilizes high-frequency pulse-width modulation (PWM) to guarantee low electromagnetic interference (EMI) and excellent efficiency. This converter achieves a wide input voltage range from 4.5V to 30V and will operate with input voltage variations as low as 4.5 volts and as high as 30 volts, saving cost on board components. The low-output ripple and low-noise feature also provides an excellent performance in audio noise reduction.The PT4243N can be used in a variety of applications. It is a great choice for low-power (less than 1A) consumer electronics, instrumentation, industrial control, and communication devices. It can also be applied in power conversion applications such as GPUs, microprocessors, and ASICs, as well as high-power applications such as servers, storage, and telecom/networking.The PT4243N operates on the basic principles of linear induction and pulse width modulation, using an integrated switching MOSFET, an inductor, an output capacitor, and a control circuit. It uses the Inductor-Output capacitor (L-C) energy transfer in order to convert the input DC power into multiple regulated outputs.The PT4243N features a fixed frequency and soft-start, adjustable output voltages, a comprehensive protection circuit (short-circuit, over-current, output overvoltage, and over-temperature), and a 100% burn-in prior to shipment. This converter also offers excellent EMI performance, high power density, low noise and voltage accuracy.The PT4243N is an ideal choice for high-efficiency DC-DC conversion solutions. With its high-frequency structure and proprietary circuit design, it can significantly reduce the power dissipation, noise, and size of the converter. Furthermore, its low-EMI performance and comprehensive protection circuit provide a safe and reliable DC power supply for any application.
