Wide supply voltage operating range: 1.8 to 15V  
The FSP3601 is a boost topology switching regulator  
control IC for battery-used applications field. The  
FSP3601 includes a totem-pole single output stage  
for driving NPN transistor or N-MOS, high precision  
reference (0.5V) for comparing output voltage with  
feedback amplifier, an internal dead-time control for  
controlling the minimum duty cycle, programmable  
soft start with short circuit protection function and  
logic level control for operating mode or standby  
mode.  
Reference voltage precision: 4%  
Low current consumption:  
Operation Mode 5.5mA  
Standby Mode: 1µA
