Средства разработки интегральных схем (ИС) управления питанием LMR14203XMKDEMO/NOPB

The LMR14203XMKDEMO/NOPB is an demonstration board for LMR14203, a PWM DC to DC buck (step down) regulator. With a wide input range from 4.5V to 42V, it is suitable for a variety of applications from automotive to power conditioning of unregulated sources. Operating frequency is fixed at 1.25MHz allowing the use of small external components while still being able to have low output voltage ripple. Soft start can be implemented using the shutdown pin with an external RC circuit allowing the user to tailor the soft start time to a specific application. The demonstration board comes populated with either the LMR14203XMK or LMR14206XMK, but can easily be modified to accommodate any of the LMR14203/06 regulator ICs.
