Product Summary

The LT1373CS8#TR is a low supply current high frequency current mode switching regulator. It can be operated in all standard switching configurations including boost, buck, flyback, forward, inverting and Cuk.A 1.5A high efficiency switch is included on the die, along with all oscillator, control and protection circuitry. All functions of the LT1373CS8#TR are integrated into 8-pin SO/PDIP packages. Compared to the 500kHz LT1372, which draws 4mA of quiescent current, the LT1373CS8#TR switches at 250kHz, typically consumes only 1mA and has higher efficiency. High frequency switching allows for small inductors to be used. All surface mount components consume less than 0.6 square inch of board space. The LT1373CS8#TR applications are: (1)Boost Regulators; (2)CCFL Backlight Driver; (3)Laptop Computer Supplies; (4)Multiple Output Flyback Supplies; (5)Inverting Supplies.
