TYPICAL APPLICATION
DESCRIPTION
The LT ? 3495/LT3495B/LT3495-1/LT3495B-1 are low noise
boost converters with integrated power switch, feedback
resistor and output disconnect circuitry. The parts control
power delivery by varying both the peak inductor current
and switch off-time. This novel* control scheme results
in low output voltage ripple as well as high efficiency
over a wide load range. For the LT3495/LT3495-1, the
off-time of the switch is not allowed to exceed a fixed
level, guaranteeing the switching frequency stays above
the audio band for the entire load range. The parts feature
a high performance NPN power switch with a 650mA
and 350mA current limit for the LT3495/LT3495B and
LT3495-1/LT3495B-1 respectively. The quiescent current
is a low 60μA, which is further reduced to less than 0.1μA
in shutdown. The internal disconnect circuitry allows the
output voltage to be isolated from the input during shut-
down. An auxiliary reference input (CTRL pin) overrides
the internal 1.235V feedback reference with any lower
value allowing full control of the output voltage during
operation. The LT3495 series are available in a tiny 10-lead
3mm × 2mm DFN package.
