描述 Description
The LMR14203 is a PWM DC/DC buck (step-down) regulator. With a wide input range from 4.5V-42V, it is suitable for a wide range of applications such as power conditioning from unregulated sources. They feature a low RDSON (0.9? typical) internal switch for maximum efficiency (85% typical). Operating frequency is fixed at 1.25 MHz 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 LMR14203 is optimized for up to 300 mA load current.Additional features include: thermal shutdown, VIN under-voltage lockout, and gate drive under-voltage lockout. The LMR14203 is available in a low profile SOT-6L package.
