The LM5000 is a monolithic integrated circuit specifically designed and optimized for flyback, boost or forward power converter
applications. The internal power switch is rated for a maximum of 80V, with a current limit set to 2A. Protecting the power
switch are current limit and thermal shutdown circuits. The current mode control scheme provides excellent rejection of line
transients and cycle-by-cycle current limiting. An external compensation pin and the built-in slope compensation allow the
user to optimize the frequency compensation. Other distinctive features include softstart to reduce stresses during start-up
and an external shutdown pin for remote ON/OFF control. There are two operating frequency ranges available. The LM5000-3 is
pin selectable for either 300kHz (FS Grounded) or 700kHz (FS Open). The LM5000-6 is pin selectable for either 600kHz (FS Grounded)
or 1.3MHz (FS Open). The device is available in a low profile 16-lead TSSOP package or a thermally enhanced 16-lead LLP package.
