DC DC Converters are an integral part and necessity for modern life as they are used in a variety of products, from consumer electronics to automotive and industrial applications. The LTM4642EY#PBF DC DC Converter is a high-performance DCBuck that is designed to convert a low voltage input source into a higher voltage output, providing power to a wide variety of applications. It is capable of supplying up to 2.8A continuous load current and up to 6A peak current.

The LTM4642EY#PBF DC DC Converter is manufactured by Linear Technology Corporation and features a maximum switching frequency of 500kHz. It has a voltage input range from 4.5V to 38V and can provide a regulated output of 3.0V-5.5V. It also includes a Spread Spectrum Mode, which reduces the electromagnetic interference (EMI) caused by the switching of the device, as well as an active current sharing feature which allows multiple LTM4642EY#PBF DC DC Converters to be paralleled for higher total current output.

The LTM4642EY#PBF DC DC Converter offers a wide range of features that make it ideal for applications such as microcontroller based systems, gate drivers, ASIC/ASSP supplies, FPGA, DSP and memory supplies. Additionally, it is capable of operating in harsh environments with minimal sacrifice in performance. Other features include: adjustable soft-start, under-voltage lockout, and thermal shutdown. Furthermore, the device includes a built-in PowerSave Mode, which allows it to enter “sleep mode” after a period of inactivity.

The LTM4642EY#PBF DC DC Converter utilizes an isolated buck converter topology which allows it to convert a DC voltage input into a regulated higher DC output voltage. It consists of two main components, a primary switching circuit and a secondary control circuit. The primary switching circuit is powered directly by the DC input voltage and includes an inductor, a diode, and a transistor switch. The secondary control circuit is powered by the output voltage and is used to drive the primary transistor switch, which flips on and off at a predetermined frequency based on the output voltage. As the primary switch turns OFF, energy is stored in inductor and then released to the output in the form of a direct current when the primary switch turns ON.

The LTM4642EY#PBF DC DC Converter provides a number of important features and capabilities which make it well suited for a variety of applications. Its high efficiency, low ripple and low noise output, and its wide input voltage range make it an ideal choice for modern power requirements. Additionally, its built-in power save mode ensures low power consumption and its active current sharing feature allows multiple converters to be paralleled for higher current output. Its rugged construction and ease of implementation further attest to its suitability for a variety of applications.
