LM5000EP

Enhanced Plastic High Voltage Switch Mode Regulator

General Description

Features

n 80V internal switch

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.
