DMA261000R is a pre-biased array of four monolithic, high-voltage, double-diffused metal-oxide silicon (DMOS) transistors. These transistors each feature three terminals, a source (S), a drain (D) and a gate (G). The DMA261000R array is used primarily in dc-dc converters as a switching and synchronizing device.

The DMA261000R performs two major functions in applications. It features a boost current driven by its high-voltage output voltage capability; this is ideal for powering low-voltage dc-dc converter and voltage regulators. The second major feature of the DMA261000R is the internal synchronizing circuit, which can easily be programmed to switch various configurable parameters, such as enable time and disable time, as per the application requirement.

The DMA261000R is a versatile, single-chip device that is capable of driving transistors and providing an optimized switch-on/switch-off process. It provides superior current-handling capabilities, enabling it to drive multiple loads in a single device. Additionally, the DMA261000R helps reduce system costs and improves overall system performance. It is also capable of maintaining a constant and continuous output voltage range and settling time, providing design engineers with the flexibility to tailor their designs for specific requirement.

The DMA261000R is designed to operate over a wide range of temperatures and to provide fast, reliable operation in high-temperature environments. It features high switching-off capacitances, which ensure short circuits can be safely and quickly disabled. Its built-in pulse width modulation (PWM) circuit allows controlling of its switching frequency, so that it can operate at a wide range of switching speeds. Furthermore, it features an internal temperature compensation circuit, ensuring that the temperature of the device is kept within an appropriate range.

The working principle of the DMA261000R is based on a four-transistor pattern made out of two independent switches connected in parallel. Each transistor is configured using one of two rated gate voltages: 15V or 30V. When a gate voltage is applied, its associated transistor is biased and turns at a particular rate (depending on its gate voltage rating). The sources of the four transistors are connected to their respective outputs and their drains are connected to their respective loads. The DMA261000R uses the switching action of the four transistors to control the on/off states of the output, depending on the selection of the transistor gate voltage.

In addition, the DMA261000R features an internal synchronizing circuit, which can be programed with various settings such as enable and disable times. This circuit helps ensure that the four transistors are properly disabled before the next transistor is enabled, significantly improving the system’s response time and providing more accurate switching. Additionally, the DMA261000R array also has an internal temperature compensation circuit, which helps keep the temperature of the device within a range of -40°C to 125°C.

The DMA261000R is an ideal choice for applications in the field of dc-dc converters, such as synchronous rectification, voltage regulation, and AC/DC conversion. It can be used to drive multiple loads, provide improved current-handling capabilities, and maintain a consistent output voltage and settling time. Furthermore, the temperature compensation circuit ensures that the device temperature is kept within a range that is suitable for reliable operation. The DMA261000R is designed to offer superior performance and reliability, making it an excellent choice for dc-dc converter and voltage regulator designs.
