Description
High Input Voltage,
Boost, Flyback, SEPIC and
Inverting Controller
The LT3758 is a wide input range, current mode, DC/DC
controller which is capable of generating either positive or
negative output voltages. It can be configured as either a
boost, flyback, SEPIC or inverting converter. The LT3758
drives a low side external N-channel power MOSFET from
an internal regulated 7.2V supply. The fixed frequency,
current-mode architecture results in stable operation over
a wide range of supply and output voltages.
The operating frequency of LT3758 can be set with an
external resistor over a 100kHz to 1MHz range, and can
be synchronized to an external clock using the SYNC pin.
A minimum operating supply voltage of 5.5V, and a low
shutdown quiescent current of less than 1A, make the
LT3758 ideally suited for battery-powered systems.
The LT3758 features soft-start and frequency foldback
functions to limit inductor current during start-up and
output short-circuit.
