DC DC Converters

The STMGFW154812-N2 DC to DC converter is designed to provide a stepped-up or stepped-down power supply for a range of devices. It is an isolated, non-isolated, or fully regulated DC to DC converter, which gives system designers the ability to convert input DC voltages to adjustable output DC voltages.The STMGFW154812-N2 can be used in a variety of applications, such as system power management, DC motor control, LED lighting, AC/DC converters, charge controllers, portable power systems, and renewable energy systems. It is also suitable for use in automotive, industrial, and medical applications.The STMGFW154812-N2 is a highly efficient, low-loss device with a wide input voltage range and a wide output voltage range. It is a one-piece integrated solution for all types of DC to DC conversion applications, with a maximum efficiency of up to 90%. It can convert up to 25A output current, and the ripple and noise is very low, ensuring high quality power supply performance.The STMGFW154812-N2 can be used to convert an input voltage from 6V to 24V to an output voltage of 5V to 66V, in either the positive or negative direction. It is designed to provide a wide range of output voltage options, allowing the user to optimize system performance. The device can be programmed to operate in different modes:• Boost mode: In this mode, the output voltage is higher than the input voltage. It is suitable for applications where the input voltage is low, like a battery or a solar cell, and the output voltage is higher, such as an LED driver.• Buck mode: In this mode, the output voltage is lower than the input voltage. It is suitable for applications where the input voltage is high, like a generator or AC supply, and the output voltage is lower, like a motor control or an embedded system.• Buck-Boost mode: In this mode, the input and output voltages can be equal or different. It is suitable for applications where the input voltage is variable, and the output voltage can be kept at a constant value.The STMGFW154812-N2 provides protection for all types of system applications, including over-temperature, over-voltage, under-voltage, over-current, short-circuit, and reverse polarity protection.The working principle of the STMGFW154812-N2 is based on an inductor-diode-capacitor topology. The inductor is used to store energy from the input and then release it to the output. The diode helps to prevent the inductor’s energy from being returned to the input. The capacitor is used to reduce the voltage ripple of the output voltage.The device has a wide dynamic operating range with excellent line regulation over the range of 5V to 66V, making it suitable for a variety of DC to DC conversion applications. In general, the device is designed to operate in either of two modes depending on the input/output configuration, the buck mode or the boost mode.In the buck mode, the input voltage is stepped down to the output voltage. The inductor stores energy during each cycle when the switch is on, and the energy is transferred to the load when the switch is off. The diode ensures that the energy stored in the inductor is not returned to the input and is available to the output.In the boost mode, the input voltage is stepped up to the output voltage. During each cycle, when the switch is on, the current flows through the inductor, storing energy. The stored energy is transferred to the output when the switch is off, creating a higher output voltage. The diode helps to ensure that the energy stored in the inductor is not returned to the input.The STMGFW154812-N2 is a highly efficient and cost effective solution for applications requiring a wide range of output voltages. It is designed to perform reliably in harsh environments, while still providing excellent levels of power efficiency. With its wide dynamic operating range and low noise operation, it is an ideal choice for a variety of DC to DC conversion applications.
