Description
The FAN7621 is a pulse frequency modulation controller
for high-efficiency half-bridge resonant converters.
Offering everything necessary to build a reliable and
robust resonant converter, the FAN7621 simplifies
designs and improves productivity, while improving
performance. The FAN7621 includes a high-side gate-
drive circuit, an accurate current controlled oscillator,
frequency limit circuit, soft-start, and built-in protection
functions. The high-side gate-drive circuit has a
common-mode noise cancellation capability, which
guarantees stable operation with excellent noise
immunity. Using the zero-voltage-switching (ZVS)
technique dramatically reduces the switching losses and
efficiency is significantly improved. The ZVS also
reduces the switching noise noticeably, which allows a
small-sized Electromagnetic Interference (EMI) filter.
The FAN7621 can be applied to various resonant
converter topologies; such as series resonant, parallel
resonant, and LLC resonant converters.
