LT1308AIS8#PBF

LINEAR TECHNOLOGY  LT1308AIS8#PBF  直流/直流开关升压逐步递增稳压器, 可调, 1V-10V输入, 1A输出, 600kHz, SOIC-8

The is a micropower fixed frequency step-up DC-to-DC Converter operate over a 1 to 10V input voltage range. It is improved versions of the LT1308 and is recommended for use in new designs. It features automatic shifting to power saving Burst Mode® operation at light loads and consumes just 140µA at no load. Low-battery detector accuracy is significantly tighter than the LT1308. The 200mV reference is specified at ±2% at room and ±3% over temperature. The shutdown pin enables the device when it is tied to a 1V or higher source and does not need to be tied to VIN as on the LT1308. An internal VC clamp results in improved transient response and the switch voltage rating has been increased to 36V, enabling higher output voltage applications.
