LT1614CMS8#PBF

LINEAR TECHNOLOGY  LT1614CMS8#PBF  直流-直流开关反相稳压器, 可调, 1V-5V输入, 24V/500mA输出, 750kHz, MSOP-8

The is a fixed frequency inverting-mode Switching Regulator operates from an input voltage as low as 1V. Utilizing a low noise topology, the LT1614 can generate a negative output down to -24V from a 1 to 5V input. Fixed frequency switching ensures a clean output free from low frequency noise. The device contains a low-battery detector with a 200mV reference and shuts down to less than 10µA. No load quiescent current of the LT1614 is 1mA and the internal NPN power switch handles a 500mA current with a voltage drop of just 295mV. High frequency switching enables the use of small inductors and capacitors. Ceramic capacitors can be used in many applications, eliminating the need for bulky tantalum types.
