LM5000EP
Enhanced Plastic High Voltage Switch Mode Regulator
General Description
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 compen-
sation allow the user to optimize the frequency compensa-
tion. 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 en-
hanced 16-lead LLP package.
