LT1308 Datasheet PDF

●The LT1308BCS8#PBF 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 continuous switching at light loads and operates at a quiescent current of 2.5mA. 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.
