Preliminary Datasheet
1.6x Linear DC Fan Driver with VOUT Fully on Control
AP2113
General Description
The AP2113 is a low dropout high performance linear
regulator which is specially designed to drive a DC
fan, the regulator delivers output current 600mA in
minimum.
The AP2113 provides low quiescent current
consumption 70µA, over current limit protection and
load short current protection with fold-back limitation
50mA, which are ideal for battery powered system
application.
The AP2113 output voltage (V_OUT) follows 1.6 times
of V_SET input voltage until it reaches V_IN voltage
minus dropout
________
voltage
(V_DROP)
at
adjustable
mode
(set FON pin logic high). The V_SET voltage must be
larger than
________
1.0V
to
guarantee
V_OUT
1.6
times
of
V_SET.
An FON pin turns V_OUT fully on when set logic low.
Features
• Output Voltage in Adjustable Mode Follows 1.6
Times of V_SET (V_OUT/V_SET=1.6±3%)
• Low Quiescent Current: 70µA (Typ)
• Guarantee 0.6A Continuous Load
• Switchable Adjustable Mode/Full Speed Mode
• Over Current Protection
• Short Current Protection with Fold-back
Limitation: 50mA
• Low Dropout Voltage:
150mV @ 600mA (Typ) at Full Speed Mode
200mV @ 600mA (Typ) at Adjustable Mode
