Original Press Release:
Fairchild Semiconductor's Highly Integrated Off-Line Power Switch Allows the Use of Smaller Size Transformers
New Power Switch Offers Improved Reliability in DC/DC Power Supply Designs
San Jose, Calif. - June 4, 2003 - Fairchild Semiconductor International (NYSE: FCS) introduces the FS6X1220RT Fairchild Power Switch (FPS), a highly integrated off-line power switch for DC/DC forward or fly-back power supply applications, as well as for VOIP (Voice Over Internet Protocol) phones, digital feature phones, industrial power supplies and telecom central office and PBX power supplies. This device integrates a fully avalanche-rated SenseFET (200V minimum breakdown rating) with a current mode PWM IC--a unique combination that minimizes external components, simplifies designs, and lowers cost in target applications. Designs based on the integrated FS6X1220RT, with its various protection circuits, enjoy performance superior to discrete MOSFET/controller or RCC switching converter solutions while benefiting from reduced board space and improved reliability.
The internal features of this new Power Switch include over-voltage, over-load, cycle-by-cycle current limit, and thermal shutdown protection. To increase system efficiency and allow the use of smaller size transformers, the FS6X1220RT uses an integrated 300kHz oscillator. The FS6X1220RT also boasts line-under voltage detection, remote sleep on/off, under-voltage lock out, and an optimized blanking and gate turn-on/turn-off driver. In addition, the device has temperature-compensated, precision current sources for loop compensation and fault protection circuitry. The internal current sensing, high-voltage SenseFET on the device offers a 200V minimum breakdown rating. This product is available in space-saving, TO-220F-5L and D2-PAK-5L packages.
The FS6X1220RT, used in conjunction with Fairchild's optically isolated error amplifiers, such as the FOD2741, enables isolated power supply designs by minimizing board space and reducing component count.
Price: FS6X1220RT US $2.11 (1,000pcs)
Availability: Samples and demo boards available now, production quantities in 8 weeks.
D2-PAK-5L will be available by June
Delivery: 8 weeks ARO
