LM3000 Dual Synchronous Emulated Current Mode Controller

The LM3000 is a dual output synchronous buck controller which is designed to convert input voltages ranging from 3.3V to 18.5V down to output voltages as low as 0.6V. The two outputs switch at a constant programmable frequency of 200 kHz to 1.5 MHz, with the second output 180 degrees out of phase fr.

LM3000 Features

* which include input under-voltage lock-out (UVLO), power good (PGOOD) signals for each output, over-voltage crowbar and hiccup mode during short circuit events. Features

* VIN range from 3.3V to 18.5V Output voltage from 0.6V to 80% of VIN R
