IPM6220EVAL1 Datasheet (Intersil Corporation) - Advanced Triple PWM Only Mode and Dual Linear Power Controller for Portable Applications

IPM6220EVAL1, Advanced Triple PWM Only Mode and Dual Linear Power Controller for Portable Applications

VBATT (Pin 1) Supplies all the power necessary to operate the chip.

The IC starts to operate when the voltage on this pin exceeds 4.7V and stops operating when the voltage on this pin drops below approximately 4.5V.

Also provides battery voltage to the oscillator for feed-forward rejection to input
