LT1950, Single Switch PWM Controller

www.DataSheet.in LT1950 Single Switch PWM Controller with Auxiliary Boost Converter DESCRIPTIO The LT®1950 is a wide input range, forward, boost, flyback and SEPIC controller that drives an N-channel power MOSFET with few external components required.

A resistor programmable duty cycle clamp can be used to generate a volt-second clamp for forward converter applications.

An internal boost switcher is available for creating a separate supply for the output gate driver, allowing 10V gate drive fro
