MAX8630Y Datasheet (Maxim Integrated Products)

MAX8630Y, Charge Pumps

The MAX8630Y/MAX8630Z charge pumps drive up to 5 white LEDs with regulated constant current up to 125mA total.

By utilizing adaptive 1x/1.5x charge-pump modes and very low-dropout current regulators, they achieve high efficiency over the full 1-cell Li+ battery input voltage range.
