Typical application

VCC section
The L6585DE is supplied by applying voltage between the VCC pin and GND pin. An under-
voltage lockout (UVLO) prevents the IC from operating with supply voltages too low to
guarantee the correct behavior of the internal structures.
An internal voltage clamp limits the voltage to around 17 V and can deliver up to 20 mA. For
this reason it cannot be used directly as a clamp for the charge pump (current peaks usually
reach several hundreds of mA), but can be easily used during startup in order to charge the
VCC capacitor or during save mode in order to keep the IC alive, for example, connecting
VCC to input voltage through a resistor.
In addition to the bulk capacitor (>1 F)it is suggested to place a 100 nF ceramic capacitor
close to VCC pin.
