Overview

Product Details

Demonstration circuit 925 features the LT3489EMS8E in a circuit specifically designed to drive large TFT/LCD displays. The demo circuit demonstrates small size and low component count in a Boost Circuit. It converts a 3.3V-6V input to 8V at 600mA, 23V at 10mA and -8V at 20mA. Since the maximum Vin of the LT3489 is 16V, this Demo circuit will work well at higher inputs. The only limitation is that the input has to be lower than the Boost converter output (8V) in order to stay in regulation. This circuit is designed to demonstrate the capacitor programmable Soft-Start feature, advantages of the 2MHz constant switching frequency and the internal 2.5A, 40V switch.
