White LED driver provides 64-step logarithmic dimming

This circuit for the white LED driver drives as many as four white LEDs from a 3.3V source and adjusts the total LED current from 1 to 106 mA in 64 steps of 1 dB each.

The white LED driver is designed for portable power applications that require white LEDs with adjustable, logarithmic dimming levels.
