PRODUCT SPECIFICATION  
FAN5026  
Pin Definitions (Continued)  
Pin  
Number Pin Name Pin Function Description  
14  
VIN  
Input Voltage. Normally connected to battery, providing voltage feed-forward to set the  
amplitude of the internal oscillator ramp. When using the IC for 2-step conversion from  
5V input, connect through 100K to ground, which will set the appropriate ramp gain and  
synchronize the channels 90° out of phase.  
15  
16  
PG1  
Power Good Flag. An open-drain output that will pull LOW when VSEN is outside of a  
10ꢀ range of the 0.9V reference.  
PG2 /  
Power Good 2. When not in DDR Mode: Open-drain output that pulls LOW when the  
REF2OUT VOUT is out of regulation or in a fault condition  
Reference Out 2. When in DDR Mode, provides a buffered output of REF2. Typically  
used as the VDDQ/2 reference.  
18  
28  
ILIM2 /  
REF2  
Current Limit 2. When not in DDR Mode, A resistor from this pin to GND sets the  
current limit.  
Reference for reg #2 when in DDR Mode. Typically set to VOUT1/2.  
VCC  
VCC. This pin powers the chip as well as the LDRV buffers. The IC starts to operate  
when voltage on this pin exceeds 4.6V (UVLO rising) and shuts down when it drops  
below 4.3V (UVLO falling).  
Absolute Maximum Ratings  
Absolute maximum ratings are the values beyond which the device may be damaged or have its useful life  
impaired. Functional operation under these conditions is not implied.
