MAX639EPA+

The MAX639EPA+ is a DC-DC switching regulator, which is widely applied in voltage regulation power supplies and other applications that require an adjustable output voltage. This Regulator Chip has an operating temperature range of -40℃ to +125℃. The MAX639EPA+ can convert the input currents from 4.7V to 36V, simulating high current and very low noise. It also comes with a wide bandwidth and fast response, making it suitable for all voltage regulating high performing applications.

The MAX639EPA+ can be used as a step-up, step-down or inverting DC-DC regulator, depending on the user’s application needs. It is designed to accurately regulate output voltage from 1.23V to 36V typical. Output current is adjustable up to 10A, while input current is adjustable up to 8A with a Delta Tj temperature of 2.5°C. The MAX639EPA+ features a high efficiency Pulse Width Modulation (PWM) architecture, which helps to keep the efficiency low at light load. The output current of this regulator can be configured between the full and light load mode, giving the user flexibility for the application.

The architecture of the MAX639EPA+ is made up of two parts: Pulse Frequency Modulation (PFM) and Voltage Mode Control (VMC). With the PFM, users are able to adjust the output frequency, while in the VMC, the user can adjust the output voltage. Both of these features together ensure excellent performance when placing the regulator under different loadings.

Another great feature of the MAX639EPA+ is its Over Current Protection (OCP). The OCP helps to protect the chip, and the external components. This protects all of the components, including the device itself, from any over-current situations, ensuring longer working life. Moreover, it also has Thermal Shutdown Protection (TSD), which will stop the chip from working at a certain temperature. The package itself has allowable power dissipation of 10w, which ensures the life of the device.

The MAX639EPA+ is a great choice for high performance applications. It offers a high efficiency, fast response, and low noise for the user, with its adjustable input and output current, adjustable voltage range and shutdown protection. Furthermore, the chip can be placed in full and light load mode, giving users the flexibility to optimize their operation for the variable loads. The MAX639EPA+ is ideal for applications that require an adjustable voltage, such as step-up, step-down, or inverting DC-DC regulator.
