Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The IW9802-21 is a digital zero-voltage switch (ZVS) AC/DC controller launched by (Renesas), which can provide an ultra-small, lightweight, low-cost and portable power supply for any AC power supply product. It has the following main characteristics:

High performance ‌ : Integrated with patented ZVS technology to achieve high-efficiency power conversion.

High-precision control ‌ : supports fixed voltage/adjustable output, voltage/current protection function.

Miniaturization ‌ : High switching frequency design reduces component volume.

Compatibility ‌ : It can be paired with industry-standard controllers (such as TL431) to achieve multi-protocol support.

The IW9802-21 device operates at high switching frequencies, significantly reducing the size of transformers and passive components. It can be used in conjunction with various third-party controllers, including the industry-standard programmable benchmark (TL431), to provide fixed-voltage or adjustable output power for RapidCharge applications. In addition, the IW9802-21 is equipped with an integrated primary side overvoltage/overcurrent protection circuit to prevent the risk of secondary side protection failure.
