会社ブログについて Mingjiada Supply and Purchase: INN3168C Series – Power Integrations InnoSwitch3-CE High-Efficiency Offline Flyback Switching ICs

Mingjiada Electronics is a long-term supplier and buyer of genuine Power Integrations INN3168C series products (including models such as INN3168C-H101-TL, INN3168C-H105-TL and INN3168C-H114-TL). This series comprises highly integrated constant-voltage/constant-current (CV/CC) off-line flyback switch-mode chips from the InnoSwitch3-CE family. Featuring an integrated 650V MOSFET and synchronous rectification driver, they are specifically designed for high-efficiency, compact power supplies up to 65W and are widely used in fast-charging adapters, consumer electronics and industrial power supplies.

INN3168C Product Overview

The INN3168C series is part of Power Integrations’ InnoSwitch3-CE platform. Its innovative architecture integrates the primary-side controller, secondary-side controller, safety-compliant FluxLink isolated feedback link, and a 650V power MOSFET with synchronous rectification driver, all within a single InSOP-24D package. This design eliminates the need for optocouplers, significantly simplifying the development and manufacture of flyback power supplies whilst enhancing system reliability and efficiency.

The INN3168C series, now available from Mingjiada, comprises various suffix models (such as H101, H105 and H114), which differ primarily in optional features such as protection response modes and cable compensation, catering to different application scenarios.

INN3168C Key Features and Benefits

1. Extremely high integration and compact design

Integrates a multi-mode quasi-resonant (QR)/CCM flyback controller, a 650 V MOSFET, secondary-side detection and synchronous rectification drive. Precise CV/CC regulation is achieved without the need for external optocouplers, significantly reducing the number of external components.

2. EcoSmart High Efficiency and Energy Saving

Efficiency of up to 94% across the full load range, with no-load power consumption below 15 mW at 230 VAC, easily meeting global energy efficiency standards such as CoC V5 and DOE Tier 6, whilst requiring minimal heat dissipation.

3. FluxLink Isolated Feedback

Built-in FluxLink technology enables precise secondary-side sampling and feedback transmission across the safety isolation barrier, ensuring excellent CV/CC accuracy that is unaffected by transformer consistency.

4. Comprehensive Protection Mechanisms

Input under-voltage/over-voltage protection (UV/OV)

Output over-voltage/over-current protection (OVP/OCP)

Secondary synchronous rectifier (SR FET) short-circuit/open-circuit detection

Over-temperature protection (configurable with hysteresis or latch)

5. Safety and Immunity

Insulation strength >4000 VAC, 100% factory HIPOT testing. Excellent noise immunity meets the EN61000-4 Series Class A performance standards, making it suitable for demanding industrial environments.

Typical Applications

With its 50W–65W power range and CV/CC characteristics, the INN3168C is ideal for the following applications:

Consumer electronics adapters and chargers: High-current fast-charging adapters for mobile phones, tablets and laptops.

Network and communications equipment: Power supplies for set-top boxes, routers, switches and gateways.

Gaming and audio-visual equipment: Power supplies for games consoles, LED displays and audio systems.

Industrial control and auxiliary power supplies: Industrial instruments, smart meters and internal auxiliary power supplies for small devices.
