Clean Switcher Powers 16 Bit A/D Converters:  07/04/94 EDN-Design Ideas / (added 6/06) The low-noise switcher in Fig 1 works much like a TV's horizontal-deflection circuit to provide clean power for a 16-bit A/D converter. In operation, Q3 is a logic-level gate-drive MOSFET driven by the same 100-kHz square wave that clocks the A/D converter. When Q3 turns off, the primary of T1 resonates with C3 and flies back to 25V. Energy then transfers to the transformer's secondary. When the flyback voltage attempts to go below ground, the integral body diode of the power MOSFET Q3 clamps the flyback voltage, causing excess resonant energy in the transformer to flow back through its primary, recharging C1. While C1 is recharging and the drain of Q3 is nearly at 0V, the gate of Q3 gets turned on again, repeating the cycle....
