LT1308ACS8#TR

LT1308ACS8#TR LINEAR TECHSKU 11632961 The LT1308A/LT1308B are micropower, fi xed frequency step-up DC/DC converters that operate over a 1V to 10V input voltage range. They are improved versions of the LT1308 and are recommended for use in new designs. The LT1308A features automatic shifting to power saving Burst Mode operation at light loads and consumes just 140"A at no load. The LT1308B features continuous switching at light loads and operates at a quiescent current of 2.5mA. Both devices consume less than 1"A in shutdown. Low-battery detector accuracy is signifi cantly tighter than the LT1308. The 200mV reference is specifi ed 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. CONV DC/DC STEP UP HC, 8SOIC
