NCV8876 Boost Design Tool Revision 2 (6OCT14)
This tool is intended to assist the user when designing with the NCV8876 for continuous conduction mode boost applications. It is intended to provide first pass values and does not replace simulation and prototyping.
The NCV8876 is a non−synchronous boost controller designed to supply a minimum output voltage during Start−Stop vehicle operation battery voltage sags. The NCV8876 is in low quiescent current sleep mode under normal battery operation (12 V) and is enabled when the supply voltage drops below the descending threshold (7.3 V for the NCV887600). Boost operation is initiated when the supply voltage is below the regulation set point (6.8 V for the NCV887600). Once the supply voltage sag condition ends and begins to increase, the NCV8876 boost operation will cease when the supply voltage increases beyond the regulation set point. The NCV8876 low quiescent current sleep mode resumes once the supply voltage increases beyond the ascending voltage threshold (7.7 V for the NCV887600).
