DC DC converters are used to convert input power from one type of DC voltage into another for various applications. They can be used to increase or decrease the voltage and current as required for the application. The LSN2-T/30-D12-C is a DC DC converter, and in this article we\'ll look at its application field and working principle.

The LSN2-T/30-D12-C is a dual-channel buck converter module with an adjustable constant-current mode. It has a wide input voltage range, from 3.3V to 5V, and can simultaneously output two fully adjustable output voltages. The maximum load current is 12A per channel, giving it a total power output of 30W. It has a low-noise and high-precision design, and its current sensing design ensures accuracy in current limiting. It can pass the EMC test of EN55032 Class B requirements for non-residential applications.

The LSN2-T/30-D12-C is suitable for driving LEDs and display modules, providing a constant current with excellent linearity. It can also be used for battery management and battery charging systems, LED lighting, security monitoring systems, and point-of-sale systems. It is highly efficient, low-noise, low-cost, and compact, making it ideal for use in small, portable electronic devices, for example, smartphones, tablets, and PDAs.

The LSN2-T/30-D12-C operates on a fixed constant-current mode, with a voltage mode also available. It employs synchronous rectification for low noise and high efficiency, with no external drive circuitry needed. The device also has an internal temperature monitor which will shut down the device if it exceeds a certain temperature, and this can be activated via an internal temperature sensor or external temperature sensor.

The device features a wide range of adjustable current settings from 0.3A to 12A, with a 0.1A resolution to ensure accurate current setting. It has a step-down output voltage range of 0.6V to 5V, and the output voltage is adjustable from an external resistor divider. The output current and voltage can be precisely adjusted by external resistors, and the over-current protection can be programmed using the external resistors. Both channels have an input voltage range of 3.3V to 5V and an efficiency of up to 96%.

The LSN2-T/30-D12-C requires a simple component count to operate, which makes it both cost-effective and easy to use. It is also equipped with a comprehensive range of protection features, including over-voltage, over-current, under-voltage, and short-circuit. It is quickly programmable, enabling precise adjustment of constant current and output voltage. Its robust design and high reliability make it ideal for a range of applications.

In summary, the LSN2-T/30-D12-C is a dual-channel DC DC converter that offers a wide range of adjustable current settings and adjustable output voltages. It is highly efficient, low-noise, and cost-effective, with a wide input voltage range and an internal temperature monitor. It is suitable for a variety of applications, including driving LEDs, charging batteries, and powering smartphones, tablets, and PDAs.
