Dc-Dc Switching Buck Step Down Regulator Adjustable 4.5V 42V In 765Mv 34V Out 600Ma Out Sot-23-6

The LMR14206XMK/NOPB is a PWM DC/DC Buck (Step-down) Voltage Regulator with a wide input range from 4.5 to 42V, they are suitable for a wide range of applications such as power conditioning from unregulated sources. They feature a low RDSON (0.9R typical) internal switch for maximum efficiency (85% typical). 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 LMR14206 is optimized for up to 600mA load current with a 0.765V nominal feedback voltage. Additional features include thermal shutdown, VIN under-voltage lockout and gate drive under-voltage lockout.
