IC7201

VHiSTRY64761E

SWING-P-CTL

This product is hybrid IC for the pseudoresonant switching power sup-
ply with built-in power MOSFET and multifunctional control IC. Highly 
effective and the low noise are achieved by a pseudoresonance and 
the bottoms ticket operation at the normal operation, and low power 
consumption is achieved at the standby by the thing that intermittent 
oscillates.
