Application Examples

within a system. By setting the T/F pin high, the LM3551/2
will allow the current to flow through the flash LED while still
maintaining the fixed output voltage rail. The flash current is
set by R

, and should not exceed 500mA. The total usable
output current is dependent upon the output voltage se-
lected. If the dual-mode configuration is used, the FTO pin
should be grounded to prevent the voltage rail from being
shutdown at an unwanted time.
