DC DC converters are widely used in various applications. Among these applications, the LW015B series is one of the most popular DC/DC converters because of its high efficiency, stability, and reliability. The LW015B series is primarily employed in medical device, industrial, and communications applications.

The LW015B series offers a wide range of input voltage ranges from 9 to 36VDC and provides an array of output voltages, including 5V, 9V, 12V, 15V, and 24V. The series has an efficiency rating of up to 95%, and can provide a constant current (up to 4A) or constant voltage power source. Moreover, this series features built-in short circuit, overload, and voltage regulation, as well as over temperature protection.

The working principle of the LW015B series relies on a switching regulator. The switching regulator is a linear regulator operating at an oscillating frequency that draws distinct on and off cycles from the input power source. The core of a switching regulator contains an inductor and a capacitor, which store and release energy. The transistor is used to drive the switching operation, while the high-speed transistors act as voltage regulators.

When the LOAD nput is connected to the input voltage (such as 10V), the voltage is compared with the reference voltage of the controller (5V). The difference between the two is used to control the switching transistor. A controllable current flows through the switching transistor and the inductor, causing it to store energy into the magnetic field. The stored energy is released into the LOAD output when the transistor switches off. The capacitor in parallel stabilizes the output voltage.

The LW015B series is ideal for applications that require high efficiency, reliable power, and adjustable output voltage. Due to its robust design and features, the LW015B series is also the best choice for many medical, industrial, and communications applications.
