ADP1650
Rev. C | Page 12 of 32
THEORY OF OPERATION
The ADP1650 is a high power, I2C programmable white LED
driver ideal for driving white LEDs for use as a camera flash.
The ADP1650 includes a boost converter and a current
regulator suitable for powering one high power white LED.
WHITE LED DRIVER
The ADP1650 drives a synchronous 3 MHz boost converter as
required to power the high power LED. If the sum of the LED
forward voltage and current regulator voltage is higher than
the battery voltage, the boost turns on. If the battery voltage is
higher than the sum of the LED VF and current regulator volt-
age, the boost is disabled and the part operates in pass-through
mode. The ADP1650 uses an integrated PFET high-side current
regulator for accurate brightness control.
MODES OF OPERATION
Once the enable pin is high, the device can be set into the four
modes of operation using the LED_MOD bits in Register 0x04,
via the I2C-compatible interface.
LED_MOD = [00] sets the device in standby mode, consuming
3 μA (typical).
LED_MOD = [01] sets the device in fixed VOUT = 5 V output
mode.
LED_MOD = [10] sets the device in assist light mode with
continuous LED current.
LED_MOD = [11] sets the device in flash mode with current up
to 1.5 A available for up to 1.6 sec.
