LTC3873 - No RSENSE Constant Frequency Current Mode Boost/Flyback/SEPIC DC/DC Controller

The LTC3873 is a constant frequency, current mode, boost, flyback or SEPIC DC/DC controller that drives an N-channel Power MOSFET in high input and output voltage converter applications. Soft-start CAN be programmed using an external capacitor.
The LTC3873 provides 1.5% output voltage accuracy and consumes only 300A quiescent current during normal operation and only 55A during micropower start-up. Using a 9.3V internal Shunt Regulator the LTC3873 CAN be powered from a high input voltage through a resistor or it CAN be powered directly from a low impedance DC voltage of 9V or less.
The LTC3873 is available in 8-lead ThinSOT and 2mm x 3mm DFN packages.
