DC760A - LT3472EDD | Boost and Inverting DC/DC Converters, Vin = 2.7V - 4.2V, Vout1 = 15V @ 25mA-45mA, Vout2 = -8V @ 35mA-65mA

Demonstration circuit 760 is a dual, output, 1.1MHz Boost/Inverter in a 3mm x 3mm DFN featuring the LT3472EDD. The demo circuit demonstrates small size and low component count in a Boost Circuit and an Inverting Circuit. The Boost Converter is designed to convert a 2.7V-4.2V input to 15V output at 25mA- 45mA load. The Inverting Circuit generates a -8V output at 35mA-65mA from the same input. Since the maximum Vin of the LT3472EDD is 16V, this demo circuit will work well at higher inputs. The only limitation is the 10V rating of the input capacitor.
