LM5000 - Regulator

General Description

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.

LM5000 High Voltage Switch Mode Regulator July 2003 LM5000 High Voltage Switch Mode.

Key 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 1.25MHz (FS Open). The device is available in a low profile 16-lead TSSOP package (available now) or a thermally enhanced 16-lead LLP package (coming in Q3CY03). Features n 80V internal sw.
