The LT1373CS8#PBF is a low supply current high frequency current-mode Switching Regulator for use with boost regulators. 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. The LT1373 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. New design techniques increase flexibility and maintain ease of use. Switching is easily synchronized to an external logic level source. A logic low on the shutdown pin reduces supply current to 12µA. Unique error amplifier circuitry can regulate positive or negative output voltage while maintaining simple frequency compensation techniques.
