ISL80083 is an integrated mini Power Management IC (mini-PMIC) for powering low-
voltage microprocessor, or applications using a single Li-Ion or Li-Polymer cell battery to power multiple
voltage rails.
ISL80083 integrates a high-efficiency 2.
5MHz synchronous step-down converter, a low-input low-dropout linear regulator, 33MHz oscillator, level shift, and input supply select.
The 2.
5MHz PWM switching frequency allows for the use of very small external inductors and ...
