LTC3895 High Efficiency 140V to 3.3V Step-Down Converter

May 2nd 2016
The LTC®3895 is a high performance step-down switching regulator DC/DC controller that drives an all N-channel synchronous power MOSFET stage that can operate from input voltages up to 140V. A constant frequency current mode architecture allows a phase-lockable frequency of up to 850kHz. ...

4V to 135V Input to —15V Output Positive-to-Negative Regulator

Sep 17th 2014
An additional useful application for the LTC3639 is to generate a negative voltage from a positive one. The part’s wide voltage range makes even large negative output voltages realizable. This figure shows the implementation of a –15V output regulator from a 4V to 135V input. Since the output is connected to the ...
