Product Summary
The LT1308BCS8 is a micropower, fixed frequency step-up DC/DC converter that operates over a 1V to 10V input voltage range. The LT1308BCS8 features continuous switching at light loads and operates at a quiescent current of 2.5mA. It consumes less than 1μA in shutdown. 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 LT1308BCS8. The applications of the device are GSM/CDMA Phones, Digital Cameras, LCD Bias Supplies, Answer-Back Pagers, GPS Receivers, Battery Backup Supplies, Handheld Computers.
