LMR34215FSC5RNXRQ1

The LMR34215-Q1 regulator is an easy-to-use synchronous step-down DC/DC converter. The device features integrated high-side and low-side power MOSFETs, delivering output current over a wide input voltage range of 4.2V to 42V. The LMR34215-Q1 employs a peak current mode control scheme to provide excellent efficiency and output voltage accuracy. A precision enable pin supports direct connection to wide input voltages or precise control of device startup and shutdown, offering design flexibility. A power good flag with built-in filtering and delay provides a true indication of system status, eliminating the need for external supervisors.
