Fairchild Semiconductor International announces the new FAN7601, a programmable frequency, current mode PWM controller that meets the International Energy Agency's (IEA) "1-Watt Initiative" aimed at reducing the world's standby power losses to below 1 Watt. With an operating frequency of up to 300kHz and an operating current of 4mA max, the FAN7601 significantly minimizes 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 off-line 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 start-up switch, further reduce power consumption. In addition, overvoltage protection (19Vinput/2.5Vfeedback), thermal shutdown, and under voltage lock out (UVLO) (12V / 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-dip package.
