Микросхема MR2920 /Shindengen/ в корпусе HSIP-7: интегральный модуль питания.
The MR2900 Series IC modules are designed for both 200V and autosensing input with a burst-mode switching function at microloads. These modules are of the partial resonance type, and are comprised of a switching device optimized for both 200V and autosensing power supply input, and a control IC. They are designed to provide the following power supply characteristics.
Characteristics
1. An ultra high-speed IGBT with 900V resistance ensures high efficiency and low noise at partial resonance.
2. An ultra high-speed IGBT with 900V resistance simplifies design for autosensing power supply input.
3. Very low power consumption at micro-loads (in burst mode).
4. Onboard start-up circuit eliminates the need for start-up resistors.
5. Soft drive circuit achieves low noise levels.
6. Excess current protection function (ton limit, primary current limit).
7. Excess voltage protection and thermal shut-down function.
8. Power supply circuits may be constructed with a minimum of external components.
9. The use of a full mold package provides benefits in insulation design.
Applications
TVs, displays, printers, VTR, DVD, STB, air-conditioners, refrigerators, and other electrical appliances, and office equipment
