pin FuncTions  
EN/UVLO (Pin 1): Enable/Undervoltage Lockout. The EN/  
UVLO pin is used to start up the LT3511. Pull the pin to 0V  
to shut down the LT3511. This pin has an accurate 1.21V  
threshold and can be used to program an undervoltage  
lockout (UVLO) threshold using a resistor divider from  
supply to ground. A 2.6μA pin current hysteresis allows  
the programming of undervoltage lockout (UVLO) hys-

third winding is used, the BIAS voltage should be lower  
than the input voltage and greater than 3.3V for proper  
operation. BIAS must be bypassed with a 4.7μF capacitor
