LINEAR INTEGRATED CIRCUIT
1.
6X LINEAR FAN DRIVER WITH VOUT FULLY ON CONTROL
DESCRIPTION
The UTC LR18115 is a low output resistance 1.
6X positive voltage linear fan driver with very low dropout voltage at up to 500mA.
The UTC LR18115 consists of an error amplifier, output stage, voltage divider, over temperature protection, current limiting scheme and Fully Control logic.
VOUT voltage follows the 1.
6 times of VSET voltage until it reaches VIN voltage.
The VSET voltage must be larger than 1V to guarantee VOUT 1.
6 times of VSET.
When given low,
VOUT can be fully turned on by FON pin.
Good regulation over
variation in line, load and temperature is al...
