Description
The InnoSwitch™3-CE family of ICs dramatically simplifies the design
and manufacture of flyback power converters, particularly those
requiring high efficiency and/or compact size. The InnoSwitch3-CE
family incorporates primary and secondary controllers and safety-rated
feedback into a single IC.
Table 1. Output Power Table.
Notes:
1. Minimum continuous power in a typical non-ventilated enclosed typical size
adapter measured at 40 °C ambient. Max output power is dependent on the
design, with condition that package temperature must be <125 °C.
2. Minimum peak power capability.
InnoSwitch3-CE family devices incorporate multiple protection features
including line over and under-voltage protection, output over-voltage
and over-current limiting, and over-temperature shutdown. Devices are
available that support the common combinations of latching and
auto-restart behaviors required by applications such as chargers,
adapters, consumer electronics and industrial systems. The devices are
available with and without cable-drop compensation.
3. Package: InSOP-24D.
