Description
The LM5000 is a monolithic integrated circuit specifically designed and optimized for flyback, boost or forward power converter applications.
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.
