design features Two Wide Input Range Monolithic Switching Regulators
Make it Easy to Fit Boost, Flyback, SEPIC and Inverting
Topologies into Tight Spaces
Bin Zhang The LT3957 and LT3958 are high power monolithic switching
regulators that can generate a positive or a negative output
from a wide range of input voltages. The LT3957 operates
over an input range of 3V to 40V, making it suitable for
everything from portable electronics to automotive and
industrial applications. The LT3958 extends the input
voltage to 80V for high voltage telecommunications
supplies. Both produce high power from a small footprint
as shown by the boost converter layout in Figure 1.
FEATURES Figure 2. A high efficiency
and very compact 3VвЂ“6V
input, 12V output boost
converter VIN
3V TO 6V By integrating the power MOSFET and
LDO onto the die, the LT3957 and LT3958
simplify converter design, shrink the
solution size and reduce cost when
compared to non-monolithic solutions. The LT3957 has an integrated
40V/30mО© N-MOSFET switch with an
internally programmed current limit of …
