The SN6501 is a
monolithic oscillator/power-driver, specifically designed
for small form factor, isolated power supplies in isolated
interface applications. The device drives a low-profile,
center-tapped transformer primary from a 3.3-V or 5-V DC
power supply. The secondary can be wound to provide any
isolated voltage based on transformer turns ratio.The SN6501 consists
of an oscillator followed by a gate drive circuit that
provides the complementary output signals to drive the
ground referenced N-channel power switches. The internal
logic ensures break-before-make action between the two
switches.The SN6501 is
available in a small SOT-23 (5) package, and is specified
for operation at temperatures from –40°C to 125°C.
