Microchip LX7178-01CSP-TR
Manufacturer No:
LX7178-01CSP-TR
Manufacturer:
Microchip
Package:
20-UFBGA, WLCSP
Description:
The LX7178 is a digitally controlled step-down regulator IC with an integrated 40mΩ high-side P-channel MOSFET and a 14mΩ low-side N-channel MOSFET. It features Microsemi’s proprietary constant-frequency hysteretic control engine for near-instantaneous correction to line/load transients. It does not require high-ESR output capacitors and incorporates energysaving “PSM” (Power Save or Pulse Skip Mode) at light loads, to extend battery life in mobile applications. The LX7178 has an I2C serial interface port for output voltage margining and monitoring if required (it can also operate in default mode). In addition it includes robust fault monitoring functions. The LX7178 will operate from 3V to 5.5V, and is available in 0.8V fixed output voltage option (no voltage divider is necessary). The output voltage can also be adjusted with an external voltage divider up to 3.3V.
