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 also provided by UTC
LR18115
.
FEATURES
* VOUT Follows 1.6 Times of VSET
* 0.3 Output Resistance @ 0.5A
* Over Temperature Protection
* Current Limiting Protection
* FON Pin to Turn VOUT Fully On
