Fairchild Semiconductor has a new PWM controller that meets the International Energy Agency's (IEA) "1-watt initiative" aimed at reducing standby power losses to below 1W.

With an operating frequency of up to 300kHz and an operating current of 4mA max, the FAN7601 a programmable frequency, current mode PWM controller significantly minimises switching losses and is therefore considered a "green" product for complying with international energy savings guidelines.

The FAN7601 requires few external components and is an ideal low-cost solution for offline switch-mode power supply (SMPS) 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, overvoltage protection (19V input/2.5V feedback), thermal shutdown, and undervoltage lock out (12/8V) enhance system reliability.

As a result of its simple board layout requirements, the FAN7601 ensures ease of use in applications, in addition to long-term reliability.

The FAN7601 complements Fairchild's other power solutions for SMPS and DC/DC conversion applications such as optocouplers, QFETs, mosfets and bridge rectifiers.

The FAN7601 is available in an 8-pin DIP.
