Fairchild Unveils FAN7601 "Green" PWM Controller

Fairchild Semiconductor International (San Jose, CA) announced the new FAN7601, a programmable-frequency, current-mode, pulse-width modulation controller that meets the International Energy Agency's "1W Initiative" aimed at reducing standby power losses to below 1W. With an operating frequency of up to 300kHz and an operating current of 4mA maximum, the FAN7601 minimizes switching losses and is considered a "green" product for complying with international energy-savings guidelines.

The FAN7601 requires few external components and is a suitable low-cost solution for off-line, switch-mode power supply and dc/dc conversion applications, as well as for adapters in notebook PC, LCD monitor, DVD, set-top box and PC auxiliary power supply applications. Internal features of the FAN7601, such as a programmable soft-start (20mS) and a startup switch, further reduce power consumption. In addition, over-voltage protection (19Vinput/2.5Vfeedback), thermal shutdown and under-voltage lockout (12V/8V) enhance system reliability.

Available now, the FAN7601 is offered in an eight-dip package. Pricing for the FAN7601N is $0.70 for 1,000 pieces. Delivery is eight weeks ARO.
