 |
|
Linear Technology has introduced a high temperature (-40 to 150°C) and high reliability version of the LTC3115-1, a synchronous buck boost converter that delivers up to 2A of continuous output current from a range of power sources.
Available in a 20 lead thermally enhanced TSSOP package, the LTC3115-1's 2.7 to 40V input and output range provides a regulated output with inputs above, below or equal to the regulated output.
The low noise buck-boost topology provides a continuous, jitter free transition between buck and boost modes, making it suitable for rf and other noise sensitive applications that must maintain a low noise constant output voltage with a variable input power source.
Efficiency of up to 95% extends run time in battery powered systems. The LTC3115-1's switching frequency is user programmable between 100kHz and 2MHz, and can be synchronised to an external clock. Proprietary buck boost pwm circuitry ensures low noise and high efficiency while minimising the size of external components.
