MAX8648ETE+T - Brand New Maxim Integrated LED Drivers
Credit Card - One-month free return and one year warranty.
- Full or Partial Refund, if the item is not as described
- Full Refund if you don't receive your order
General Description
The MAX8647/MAX8648 drive up to six white LEDs or two sets of RGB LEDs with
regulated constant current for display backlight and fun light applications.
By utilizing an inverting charge pump and extremely low dropout adaptive
current regulators, these ICs achieve very high efficiency over the full
1-cell Li+ battery voltage range and even with large LED forward voltage
mismatch. The 1MHz fixed-frequency switching allows for tiny external
components. The regulation scheme is optimized to ensure low EMI and low input
ripple. The MAX8647/MAX8648 include thermal shutdown, open and short-circuit
protection.
The MAX8647 features an I2C serial port, while the MAX8648 features a three-
wire serial-pulse logic interface. Both devices support independent on/off and
dimming for main and subbacklights. The dimming ranges are pseudo-logarithmic
from 24mA to 0.1mA and off in 32 steps. Both devices include a temperature
derating function to safely allow bright 24mA full-scale output current
setting while automatically reducing current to protect LEDs at high ambient
temperatures above +60°C.
The MAX8647/MAX8648 are available in a 16-pin, 3mm x 3mm thin QFN package
(0.8mm max height).
