DC DC converters provide controllable solutions to a variety of power-handling problems and are now responsible for supplying the majority of the world\'s electrical power. The LSN2-T/16-W3-C is a micro-controller-controlled, high current DC/DC converter designed to provide high efficiency and high power solutions for demanding applications.

Application Field

LSN2-T/16-W3-C designed for applications in telecommunications, consumer electronics, heavy automotive, industrial, portable, power management and 100-Watt/plus power systems. It is well suited for low-voltage, high-current applications such as charging batteries and powering small motors. The power dissipation can be adjusted to the suitable value for the load. It is also suitable for the operating at the constant current of the applications such as LED Driver and Motor Drive.

Working Principle

The LSN2-T/16-W3-C operates by using a chopper technique. This technique consists of a pulse width modulated (PWM) oscillator that switches a high current transistor on and off in a controlled manner. The duty cycle and frequency of the PWM signal is proportional to the output voltage of the converter. When the PWM output is high, the transistor is driven into saturation and the voltage across the load decreases. When the PWM output is low, the transistor is reversed biased and the voltage across the load increases.

It is designed to operate at a switching frequency of 25 KHz with a specification of 1500 V isolation from input to output. This means that the converter can be used in an environment with a noise of up to 15 kV/m without interfering with the performance of the converter. The converter has several protection features including an over-temperature shut-off, over-voltage protection, and a professional boot sequence. All these parameters increase the reliability of the converter and ensure it operates well within its working specification.

LSN2-T/16-W3-C has good THD performance under non-linear loads, which means that this converter can be used for powering sensitive electronic components such as LEDs. The safety-level is EN 60664 and the EMI performance is EN 55022 Class B. This ensures that LSN2-T/16-W3-C is safe to use and will not generate interference.

In summary, the LSN2-T/16-W3-C offers the user a reliable and versatile high current DC/DC converter, with a wide range of application fields including telecommunications, consumer electronics, heavy automotive, industrial, portable, and power management. Its high performance, as well as its safety and EMI performance, make it an ideal choice for high-power applications.
