Part Details

5V at 1A from a Single Li-Ion Cell
3.3V at 300mA from a Single NiCd Cell
Low Quiescent Current: 100µA
Operates with V_IN as Low as 1V
Fixed Frequency Operation: 600kHz
Current Mode PWM Delivers Low Output Ripple
Guaranteed Start-Up into Full Load
Low Shutdown Current: 3µA
Low-Battery Comparator
Automatic Burst Mode^™ Operation at Light Load
Low V_CESAT Switch: 300mV at 2A

The LT1308 is a micropower, fixed frequency boost DC/DC converter that operates from an input voltage as low as 1V. Capable of delivering 5V at load current of 1A from a single Li-Ion cell, the LT1308 also features power saving Burst Mode operation at light loads. High efficiency is maintained over a broad 1mA to 1A load range.

The device contains a low-battery detector with a 200mV reference and shuts down to less than 5µA quiescent current. No-load quiescent current is 100µA and the internal NPN power switch handles a 2A current with a voltage drop of just 300mV.

High frequency 600kHz switching allows the use of small, surface mount components. The LT1308's current mode architecture provides fast response to load and line variations. The device is available in an 8-lead SO package.
