The LM5000EP 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 LM5000-3EP is pin selectable for either 300kHz (FS Grounded) or 700kHz (FS Open). The LM5000-6EP 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. |
