nn Available in 5mm × 6mm 36-Lead QFN Package The LT®3964 is a dual synchronous step-down DC/DC
converter with I2C interface designed to operate as a
constant-current and constant-voltage source and is ideal
for driving LEDs. The fixed frequency and peak current
mode topology result in stable operation over a wide range …
