INN3073M-H606-TL Converter Offline Flyback, Secondary Side SR Topology 25kHz ~ 95kHz MinSOP-16A
Power Integrations InnoSwitch3-TN CV/CC QR Flyback Switcher ICs
Power Integrations InnoSwitch3-TN CV/CC QR Flyback Switcher ICs are high-efficiency offline ICs with a 725V primary MOSFET, synchronous rectification, and integrated secondary side-control. The InnoSwitch3-TN ICs dramatically increase the efficiency of auxiliary power supplies used in appliances, consumer products, and industrial applications. Ideal for isolated and non-isolated designs, these advanced flyback controllers can achieve up to 90% full load efficiency, flat efficiency across the load range, and very low no-load consumption. The InnoSwitch3-TN components may be used as an accurate 5V single-output power supply, with two positive rails or with both positive and negative rails.
The 725V primary MOSFET and the primary/secondary flyback controllers are coupled using the proprietary FluxLink communications channel. Safety-rated FluxLink communication ensures reliable synchronous rectification and accurate output CV and CC. Comprehensive safety features include output over-current protection and over-temperature protection. The small MinSOP package and a low number of external components make the InnoSwitch3-TN ICs ideal for compact designs.
