FSL206MRx Series Eliminates Auxiliary Bias Winding, Simplifies Design
SAN JOSE, Calif. — (BUSINESS WIRE) — June 18, 2012 — Switch mode power supply (SMPS) designers need space-saving, cost- effective power supply solutions with high energy efficiency, optimized system performance and improved reliability. To help meet these design complexity challenges, Fairchild Semiconductor (NYSE: FCS) has developed the FSL206MRx integrated Pulse-Width Modulator (PWM) controller.
Part of the FPS™ Green Mode Fairchild power switch device family, the FSL206MRx series is designed for high-performance offline SMPS that require minimal external components. The highly integrated PWM controller with avalanche-rugged SenseFET includes an internal regulator, eliminating the need for an auxiliary bias winding and 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, the FSL206MRN and FSL206MRL can reach a power loss of 150mW with no-bias winding and 25mW with bias winding at no-load condition when the input voltage is 265VAC. Additionally, the FSL206MRx series 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.

Features and Benefits:
- Precision fixed operating frequency: 67kHz
- Frequency modulation for attenuating electromagnetic interference (EMI)
- Built-in soft-start and startup circuit prevents transformer saturation
- No need for auxiliary bias winding
- Low under voltage lockout (UVLO)
- Ultra-low operating current: 300µA
- Separated high- and low-voltage pins to avoid creepage
- Various protection features: OLP, OVP, AOCP, TSD and LS for higher reliability
Part of Fairchild’s comprehensive portfolio of flyback converters that offer first-class performance in fewer components, the FSL206MRx devices help designers meet the engineering challenges they face by providing the technology and process advancements that result in increased performance and functional integration in less design time.
