The LT3905’s internal 65V, 350mA high efficiency switch offers output voltages as high as 60V while its 2.7V to 12V input voltage range accommodates a wide range of input sources. Its switching frequency is user selectable at 1MHz or 2MHz, enabling the designer to optimize efficiency while minimizing the size of the external components. Constant frequency architecture is used to minimize output noise. Other features include soft-start, internal compensation and programmable VIN undervoltage lockout.
The LT3905EUD is available in a 3mm x 3mm QFN-16 and is priced starting at $2.55 each in 1,000-piece quantities. An industrial grade version, the LT3905IUD, is tested and guaranteed to operate from a -40°C to 125°C operating junction temperature and is priced starting at $2.81 each in 1,000-piece quantities. Both versions are available from stock. For more information, visit www.linear.com/product/LT3905.
