Overview
19-3689; Rev 1; 2/07 EVAALVUAAILTAIOBNLEKIT 125mA 1x/1.
5x Charge Pumps for 5 White LEDs in 3mm x 3mm TDFN MAX8630Y/MAX8630Z General Description 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.
The 1MHz fixed-frequency switching allows for tiny external components, and the regulation scheme is optimized to ensure low EMI and low input ripple.
An integrated derating function protects the LEDs from overheating during high ambient temperatures.
The MAX8630Y/MAX8630Z are factory trimmed for fullscale LED current options of 15mA, 18mA, 20mA, and 25mA.
The MAX8630Z uses two enable inputs (ENM for 3 main LEDs and ENS for 2 sub LEDs) for simple on/off control and single-wire, serial-pulse dimming in 32 linear steps.
The MAX8630Y uses a single direct PWM input (P...
