Minimize Components, Achieve Higher Power
Conversion Efficiency
SMPS designers face several design complexities: space constraints, along with
the need for cost-effective power supply solutions with high energy efficiency,
optimized system performance and improved reliability. Fairchild now offers a
solution: the FSL206MR integrated pulse width modulator (PWM) controller.
With integrated protection circuitry, the controller improves SMPS reliability and
saves board space.
Part of the Green Mode Fairchild Power Switch (FPS^™) device family, the
integrated PWM controller with avalanche-rugged SenseFET includes an internal
regulator, eliminating the need for an auxiliary bias winding. This highly integrated
PWM controller includes a built-in, high-voltage startup and full-protection
circuitry that saves board space and total bill of material (BOM) costs. Optimized
for efficiency and power dissipation with burst-mode operation, when the input
voltage is 265V_AC , the devices can reach power loss of 150mW with no-bias
winding and 30mW with bias winding at no-load condition.

Design Support:
The FSL206MRx family is supported by
Fairchild’s Power Supply WebDesigner (PSW),
an easy-to-use, powerful online design tool
that allows designers to further customize and
fine tune their designs without having to build a
bench prototype.
