MAX8630Y/MAX8630Z
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 volt-
age 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 full-
scale 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
(PWM) to control all 5 LEDs with DC current proportional
to the PWM duty cycle. If both ENM and ENS (or PWM)
are kept low for more than 4ms, the MAX8630_ enters
shutdown. The MAX8630Y/MAX8630Z are available in a
14-pin, 3mm x 3mm TDFN package (0.8mm max height).
