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.

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

winding and 30mW with bias winding at no-load condition.

Advantages

• Lowpowerconsumption

of25mWwithno-load

• Noauxiliarybiaswinding

• Saves50%boardspace,

DesignSupport:

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.

EvaluationBoard

Integrated PWM Controller Evaluation Board

is now available featuring the FSL206MRN,

a PWM controller with integrated MOSFET.

This board targets 5W auxiliary power

supply applications.

The Power Supply WebDesigner and evaluation

board are both available at:
