Adapters
The adapter trend goes towards a significantly higher efficiency level, especially in partial load
conditions, as well as towards their miniaturization (slimmer and lighter). Adapters require ICs
enabling high efficiency with good EMI performance and low standby power, high performance
MOSFETs in small packages and protections for high reliability and safety. For this purpose,
ST offers a wide portfolio of dedicated ICs including PFC controllers working in Transition
Mode (TM), smart analog controllers for HB-LLC resonant circuits as well as for synchronous
rectification (dedicated to flyback/forward or HB-LLC circuits). The new combo controller
(STCMB1) is able to manage both PFC and DC-DC stages. In addition to the high-voltage
MDmesh™ MOSFETs series and the low-voltage STripFET MOSFETs, new FERD diodes,
new STRVS protections against repetitive over-voltages and voltage reference complete our
silicon offer for adapter needs. ST’s DC-DC converters guarantee high power density for post-
regulation. The ST devices best suited for each of the most common topologies are listed in
the following table.
