Product Details

The InnoSwitch3-CP family of ICs dramatically simplifies the design and manufacture of flyback power converters, particularly those requiring high efficiency and/or compact size. The InnoSwitch3-CP family incorporates a high-voltage primary-side switch, primary and secondary controllers, and safety-rated feedback into a single IC. These 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 quick charge and USB PD designs. The devices are available with and without cable-drop compensation.

Product Highlights

Highly Integrated, Compact Footprint

• Quasi-Resonant (QR) / CCM flyback controller, high-voltage primary-side switch, secondary-side sensing and synchronous rectification driver
• Integrated FluxLink, HIPOT-isolated, feedback link
• Easily interfaces to load-directed and fast-charge protocol ICs
• Constant Power (CP) Profile minimizes charging time with continuous adjustment of output current and voltage
• Accurate CV/CC/CP, independent of external components
• External IS resistor allows custom CC programming
• Instantaneous transient response with 0%-100%-0% load step

PowiGaN Technology

• PI’s proprietary gallium nitride technology
• Up to 100 W output without heatsinks
• INN3278, INN3279 and INN3270

EcoSmart – Energy Efficient

• Up to 95% efficiency across full load range
• Less than 30 mW no-load including line sense
• Easily meets all global energy efficiency regulations
• Low heat dissipation

Advanced Protection / Safety Features

• Secondary Switch or diode short-circuit protection
• Open SR FET-gate detection
• Fast input line UV/OV protection

Optional Features

• Cable-drop compensation 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 Compliance

• 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)
