INN3279C Datasheet | Power Integrations

Features - Secondary switch or diode short-circuit protection - Open SR FET-gate detection - Fast input line UV/OV protection Optional Features - Cable-drop pensation with multiple settings - Variable output voltage, constant current profiles - Auto-restart or latching fault response for output OVP/UVP - Multiple output UV fault thresholds - Latching or hysteretic primary over-temperature protection Full Safety and Regulatory pliance - Reinforced isolation - Isolation voltage >4000 VAC - 100% production HIPOT testing - UL1577 isolation voltage 4000 VAC (max), TUV (EN62368-1), CQC (GB4943.1) and DIN VDE V 0884-11 safety approved - Excellent noise immunity enables designs that achieve class “A” performance criteria for EN61000-4 suite; EN61000-4-2, 4-3 (30 V/m), 4-4, 4-5, 4-6, 4-8 (100 A/m) and 4-9 (1000 A/m) Green Package - Halogen free and Ro HS pliant Applications - High efficiency flyback designs up to 100 W - USB PD / QC / proprietary protocol chargers Description The Inno Switch™3-CP family of ICs dramatically simplifies the design and manufacture of flyback power converters, particularly those requiring high efficiency and/or pact size. The Inno Switch3-CP family incorporates primary and secondary controllers and safety-rated feedback into a single IC. Inno Switch3-CP family devices incorporate multiple protection features including line over and undervoltage protection, output overvoltage and over-current limiting, and over-temperature shutdown. Devices are available that support the mon binations of latching and auto-restart behaviors required by applications such as quick charge and USB PD designs. The devices are available with and without cable-drop pensation. SR FET FWD SR GND BPS FB D Inno Switch3-CP Primary Switch and Controller V BPP Figure 1. Typical Application Schematic.
