5x/2x Charge Pump for Backlight/Flash/RGB LEDs General Description The MAX1707 provides complete light management for main display backlight, subdisplay backlight (or RGB indicator), and white LED camera flash with regulated constant current up to 610mA total.
By utilizing adaptive 1x/1.
5x/2x charge-pump modes and very-lowdropout current regulators, it achieves high efficiency over the full 1-cell Li+ battery input voltage range.
The 1MHz fixed-frequency switching allows for tiny external components while 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 MAX1707 features an internally trimmed reference to set the maximum LED current.
An I2C† serial port is used for on/off control and setting the LED currents in 32 linear steps.
When using the RGB ind...
