1. Introduction Board L5973 Step Down

 

 

 

     L5973D Step down is a pulse source board that uses the L5973D IC with up to 2.5A load current, 250KHz high current response. . This circuit board is ideal for projects that require switching from high to low DC (DC).

     Board allows input voltage 5-35V AC / DC, 2 outputs at the same time:

    - One output with 5 output voltages, 5V, 4V, 3.3V, 2.7V or 1.8V suitable for most GSM / GPRS / GPS modules, microcontroller lines, microprocessor ... Output voltage Selected via a "select jumper" on the board.

    - One output with a fixed voltage 3V3 for the microcontroller, the voltage microprocessor uses 3V3 voltage.

     L5973D Stepdown can both provide power for two applications at the same time, very convenient and easy to use.
