Packages The LT®3959 is a wide input range, current mode, DC/DC
controller which is capable of regulating either positive or
negative output voltages from a single feedback pin. It can
be configured as a boost, SEPIC or inverting converter. n It features an internal low side N-channel MOSFET rated
for 6A at 40V and driven from an internal regulated supply provided from VIN or DRIVE. The fixed frequency, …
