LTM4651IY#PBF

LTM4651 is an ultralow noise, DC/DC μModule® inverting topology regulator. It regulates a negative output voltage (VOUT–) from a positive input supply voltage (VIN), and is designed to meet the radiated emissions requirements of EN55022. Conducted emission requirements can be met by adding standard filter components. Included in the package are the switching controller, power MOSFETs, inductor, filters and support components. Despite being an inverting topology regulator, no level shift circuitry is needed to interface to the device’s RUN, PGOOD or CLKIN pins; those pins are referenced to GND. It is widely used in application such as avionics, industrial control and test equipment, video, imaging and instrumentation, 48V telecom and network power supplies, RF systems etc.
