FAIRCHILD Semiconductor, represented by Arrow Electronics , has announced a new PWM controller that meets the International Energy Agency's ‘1-Watt Initiative’ aimed at reducing standby power losses to below one watt.
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 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 (19V input/2.5V feedback), thermal shutdown, and undervoltage lock out (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.
