Application Example
Application Description
The IC is meant to be used with a DC power supply. The power charge pump limits the
energy that is needed to drive the load at the output Q of the IC. The energy is stored to
a capacity
C
C, connected to pin C. When pin C reaches VC,off, the power charge pump is
switched off. Since the power supply consists of the inductance and a parasitic series
resistance, the remaining available energy is dissipated in the external power supply and
therefore does not stress the IC with this dispensable energy. The very low drop
regulator is provided with the energy, stored in
C
C. The regulator requires an output
capacitor
C
Q for the stability of the regulating circuit. Stability is guaranteed at values
above 22
F and an ESR ≤ 1 within the operating temperature range.
