DC DC Converters

DC-DC converters are widely used in many industries, such as automotive, telecommunications, medical, consumer, and military applications. One such device is the MPD5S025S, a highly efficient, non-isolated DC-DC converter designed for use in industrial, and automotive applications. This article will discuss the application field and working principle of the MPD5S025S.

Application Field

The MPD5S025S is a 25W, 5V DC-DC converter that is suitable for use in industrial, automotive, and other applications where a high efficiency non-isolated DC-DC converter is required. The MPD5S025S is characterized by its small size, high efficiency, and low standby power consumption.

The MPD5S025S is available in three different form factors to meet the requirements of different applications: a flat-pack with discrete lead frame, an SIP package, and a through-hole 0.50” x 0.80” (12.7mm x 20.3mm) package for use in automated assembly lines. The converter is designed to operate over an extensive input voltage range of 4.5V to 14V, and has a maximum output current of 4.2A.

The MPD5S025S provides superior performance for use in automotive applications. This includes an operational temperature range of -40°C to +85°C (at the baseplate), as well as a high efficiency of up to 96% at a full load. This ensures a high power output at a low temperature, saving energy and extending product lifetimes. The device also features a short-circuit protection and thermal protection, for added safety on the application circuit.

Working Principle

The MPD5S025S operates using a non-isolated buck topology, such as typical for non-isolated DC-DC converters. The input voltage is converted to a high-frequency pulse-width modulation (PWM) or level-shifted pulse-width modulation (LSPWM) signal and then applied to a buck-boost converter. The output voltage is regulated by adjusting the duty cycle of the applied PWM or LSPWM signal.

The MPD5S025S is designed with a fixed frequency of 250kHz, providing a high switching frequency and an extended range of inductance values, for additional flexibility. The device also features a Low Drop-out (LDO) circuit, which is used to maintain an output voltage accuracy of ±2%. This allows the device to operate even at very low input voltages.

The device also features an over-voltage protection (OVP) function, which actively limits the maximum output voltage. This is useful for applications that require the output voltage to be limited to a certain range, such as those used in automotive applications.

The MPD5S025S is equipped with an enable function, which allows the user to enable or disable the output. This feature is especially useful in applications where the DC-DC converter needs to be activated or deactivated according to a certain condition.

Conclusion

The MPD5S025S is an efficient, non-isolated DC-DC converter designed for use in industrial, and automotive applications. It offers a high efficiency of up to 96%, as well as an operational temperature range of -40°C to +85°C and an extended range of inductance values for additional efficiency. The device also features a number of safety features, such as an over-voltage protection and short-circuit protection.
