The InnoSwitch-CP architecture is revolutionary in that the devices incorporate both primary and secondary controllers, with sense Output Power Table elements and a safety-rated feedback mechanism into a single IC. 85-265 VAC 3 Close component proximity and innovative use of the integrated Product Peak or 1 Adapter 1,2 communication link permit accurate control of a secondary-side Open Frame synchronous rectification MOSFET and optimization of primary-side INN2214K 15 W 20 W switching to maintain high efficiency across the entire load range. Additionally, the minimal DC bias requirements of the link, enable the INN2215K 20 W 25 W system to achieve less than 10 mW no-load. 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. 3. Package: K: eSOP-R16B. Figure 3.
