Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

The IW9802-07 is a digital zero-voltage switch (ZVS) AC/DC controller launched by (Renesas), mainly used in high-efficiency and compact power supply designs. The IW9802-07 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.

The main features include:

High switching frequency

The patented adaptive ZVS control enables high efficiency and low EMI

User-configurable ZVS timing can optimize the performance of MOSFETs of different powers

Adaptive seamless multi-mode control (MMC) can enhance efficiency and eliminate audible noise

Ac plug and pull detection and X-cap discharge

IW9802-07 provides adequate protection for the following aspects:

Overvoltage (OVP

Overcurrent (OCP

Users can configure over-temperature

"Breakdown"

Overvoltage protection/undervoltage protection

V-induced/I-induced short circuit

Output short circuit

Additional primary side overcurrent protection (OCP) and overvoltage protection (OVP) (in case the optocoupler fails)

Application scenarios

The IW9802-07 is suitable for scenarios that require high-efficiency and small-sized power supplies, such as fast charging adapters and portable device power supplies. ‌

• 1.Is the inventory and price seen on the platform accurate?

  A: all online goods on the shelves can be ordered online, but considering the large liquidity of spot inventory, it is not possible to achieve 100% accuracy at present. In case of any abnormality, you can contact our company online and give the corresponding solution.

• 2.Are all our products genuine?

  A: our self-supporting products are from cooperative domestic and foreign original factories or authorized agents, and the source can be traced to ensure the original and authentic products.

• 3.Can you provide the qualification certificate of the original factory or agent?

  A: at present, our self-employed brands TI，ST，ADI，NXP，LATTICE，CYPRESS，INFINEON，XILINX and other first-line brands. Other channels are the original factory and agency channels. If necessary, we can communicate and confirm according to the specific brand and model.

• 4.Can I make an inquiry through the company's website?

  A: You can inquire through the website, or by phone and email.

• 5.When can I deliver the goods after placing an order? How long will it take to get there?
