DC3006A

DC3006A is a LT3001 micropower no-opto isolated flyback converter with 65V/1.2A switch demonstration board. Demonstration circuit 3006A is a compact no-opto isolated flyback converter featuring the LT®3001. The DC3006A outputs 12V and maintains tight regulation with as load current from 1.5mA up to 300mA over an input voltage from 4V to 32V. The output current capability increases with the input voltage. Transformer leakage inductance causes a voltage spike on the primary side after the power switch turns off. The leakage inductance spike is limited within the MOSFET’s voltage rating of 65V with an RC snubber and a TVS clamp which damp the ringing and clamp the MOSFET drain voltage to a safe level.

• 100mV output voltage ripple (peak to peak) at VIN = 12V, IOUT = 0.2A, TA = 25°C
