  • description

    The LT®3150 drives a low cost external N-channel MOSFET as a source follower to produce a fast transient response, very low dropout voltage linear regulator.LT®3150驱动器的低成本外部N沟道MOSFET的源跟随器产生一个快速的瞬态响应,非常低压差线性稳压器。 Selection of the N-channel MOSFET RDS(ON)allows dropout voltages below 300mV for low VINto low VOUTapplications.选择的N沟道MOSFET的RDS(ON),可以应用到低V低VOUT电压低于300mV的压差。

    The LT3150 includes a fixed frequency boost regulator that generates gate drive for the N-channel MOSFET.LT3150包含一个固定频率的升压稳压器,生成N沟道MOSFET栅极驱动。 The internally compensated current mode PWM architecture combined with the 1.4MHz switching frequency permits the use of tiny, low cost capacitors and inductors.1.4MHz的开关频率相结合,内部补偿的电流模式PWM架构允许使用纤巧,低成本电容器和电感器。

    The LT3150's transient load performance is optimized with ceramic output capacitors.LT3150的瞬态负载性能进行了优化与陶瓷输出电容器。 A precision 1.21V reference accommodates low voltage supplies.一个精确的1.21V参考适应低电压电源。

    Protection includes a high side current limit amplifier that activates a fault timer circuit.保护包括高侧电流限制放大器,激活故障定时器电路。 A multifunction shutdown pin provides either current limit time-out with latchoff, overvoltage protection or thermal shutdown.闭锁,过压保护或热关断任何一个多功能的停机引脚提供电流限制超时。 Independent shutdown control of the boost converter provides on/off and sequencing control of the LDO output voltage.独立的关断控制的升压转换器提供/关闭和测序LDO的输出电压控制。
