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 MAX8645X/MAX8645Y charge pumps drive up to eight white LEDs with regulated
constant current for uniform intensity. The main group of LEDs (M1–M6) can be
driven up to 30mA per LED for backlighting. The flash group of LEDs (F1 and
F2) is independently controlled and can be driven up to 200mA per LED (or
400mA total). Two 200mA LDOs are on-board to provide power for camera
functions. The LDOs’ output voltages are pin programmable to meet different
camera-module requirements. The MAX8645X and MAX8645Y differ only in LDO
output voltages. By utilizing adaptive 1x/1.5x/2x charge pump modes and very-
low-dropout current regulators, the MAX8645X/MAX8645Y achieve high efficiency
over the full 1-cell lithium-battery 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.
The MAX8645X/MAX8645Y are available in a 28-pin TQFN, 4mm x 4mm (0.8mm max
height) lead-free package.
