LTC3873-5 - No RSENSE Constant Frequency Current Mode Boost/Flyback/SEPIC DC/DC Controller

The LTC3873-5 is a constant frequency current mode controller for boost, flyback or SEPIC DC/DC converters designed to drive an N-Channel MOSFET for high input and output voltage converter applications.
The LTC3873-5 provides 1.5% output voltage accuracy and consumes only 300A quiescent current during normal operation and only 50A during micropower start-up. Using a 9.3V internal Shunt Regulator the LTC3873-5 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. Soft-start CAN be programmed using an external capacitor.
The LTC3873-5 is available in 8-lead ThinSOT and 2mm 3mm DFN packages.
