The LT1 619 is guaranteed to start with a minimum VIN of 1.85V. Comparator A2 senses the input voltage and gen- erates an undervoltage lockout (UVLO) signal if VIN falls below this minimum. While in undervoltage lockout, Vc is pulled low and the LT1619 stops switching. The supply current drawn by the device falls t0 140aA.
