LV58063MC Step-down Switching Regulator

Internal high side nmos fet boot strap capacitor Equivalent Circuit VIN CBOOT SW Low side MOS 2 VIN Input Voltage Pin. Large Filter Capacitor ( equal or larger than 20μF) should be connected between VIN and GND to eliminate noise on the input and to operate properly. See BOOT 3 SW Power S.

Ordering number : ENA2120 LV58063MC Bi-CMOS LSI Step-down Switching Regulator Overview http://onsemi.com LV58063MC is a 1ch step-down switching regulator. 0.13Ω FET is incorporated on the upper side to achieve high-efficiency operation for large output current. Low-heat resistance and compact-package SOP8L (200mil) employed. Current mode control gives superior load current response with easy phase compensation. EN pin, allowing the standby mode with the current drain of 70μA. Pulse-by-pulse .
