Applications • Use with InnoMux for Energy Star 8 and CEC for monitors and TVs Output Power TableDescription 85-265 VAC ProductBV3 The InnoSwitch3-MX dramatical y simplifies the development and RatingNominalMax manufacturing of multiple output power supplies, particularly those in Continuous1Continuous2 compact enclosures or with high efficiency requirements. The INN34x4C 650 / 725 V 18 W 23 W InnoSwitch3-MX architecture is revolutionary in that the devices INN34x5C 650 / 725 V 22 W 28 W incorporate both primary and secondary control ers, with sense elements and a safety-rated feedback mechanism into a single IC. INN34x6C 650 / 725 V 28 W 35 W INN3467C 650 V 35 W 44 W Close component proximity and innovative use of the integrated communication link, FluxLink, permit accurate control of a secondary- INN3477C 725 V 32 W 40 W side synchronous rectification MOSFET with Quasi-Resonant switching INN3468C 650 V 40 W 50 W of primary integrated high-voltage switch to maintain high efficiency across the entire load range. Table 1. Output Power Table. Notes: This version of InnoSwitch3 is intended to be used with InnoMux for 1. Continuous power using nominal primary current limit in a typical open frame multiple output, single-stage power supplies for monitors and TVs. application at +50 °C ambient with adequate PCB thermal design to ensure package temperature <125 °C. This enables very high system efficiency on a small PCB foot print. 2. Continuous power using maximum primary current limit in a typical open frame application at +50 °C ambient with adequate heat sinking to ensure package temperature <125 °C. 3.
