DC DC Converters

ALQ25B50N is a high-efficiency non-isolated DC/DC step-down converter with a wide input voltage range from 8.5 to 60V and a maximum output current of 25A. It is available in SOT-89, through-hole, and surface mount package. The maximum output voltage is 5V.

It has an on-board DC input which is connected to the power source directly and an adjustable output which is connected directly to the load. Its features include an overvoltage protection (OVP), a thermal shutdown (TSD) function, a current limiting (CL) circuit, and a standby function.

The ALQ25B50N is an ideal choice for applications where a stable, reliable, and efficient power supply is needed. It is suitable for various automotive, industrial, and consumer applications such as motor controllers, LED drivers, electronic radio amplifiers, and displays.

ALQ25B50N\'s working principle is quite simple. It regulates the voltage and current by controlling the switching frequency of an internal power MOSFET. When the input voltage is higher than the output voltage, the MOSFET is turned on, and the current flows through the MOSFET from the input to the output. When the input voltage is lower than the output voltage, the MOSFET is turned off, thus preventing current from flowing. The output voltage is regulated by controlling the duty cycle of the MOSFET.

ALQ25B50N has a wide input voltage range, high efficiency, and fast transient response. It is designed to be protected against short-circuit, thermal overload, excessive current, and input over-voltage. It also features an on/off control signal, and an adjustable/fixed frequency system.

Overall, ALQ25B50N is a reliable and efficient DC/DC converter. It has all the necessary features and offers a highly stable and consistent output power. It has a wide input voltage range and is suitable for various applications where a dependable and energy efficient power supply is needed.
