LINEAR TECHNOLOGY  LT1372HVCS8#PBF  直流-直流开关升压, 反相稳压器, 可调, 2.4V-30V输入, 1.25V-42V输出, 1.5A输出, SOIC-8

The is a monolithic high frequency Switching Regulator for use with CCFL backlight driver. 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 LT1372 typically consumes only 4mA quiescent current and has higher efficiency than previous parts. High frequency switching allows for very small inductors to be used. All surface mount components consume less than 0.5 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.
