Description
The 2A0565 is an electronic component belonging to the CoolSET™ F2 family and is used for low power standby and protection features. It has several special enhancements that make it suitable for various applications. The device switches to Auto Restart Mode in case of failure modes like open loop, overvoltage or overload due to short circuit, which is controlled by the internal protection unit. Furthermore, it uses frequency reduction in standby mode to lower the power consumption and support a stable output voltage in this mode.
Specifications and features
The 2A0565 is a 650V/800V avalanche rugged CoolMOS™ that requires only a few external components. It has an input Vcc Undervoltage Lockout and a 67kHz/100kHz switching frequency, with a maximum duty cycle of 72%. The device has a low Power Standby Mode to meet European Commission Requirements, thermal shutdown with Auto Restart, and overload and Open Loop Protection. The 2A0565 also has adjustable Peak Current Limitation via an external resistor, an overall tolerance of Current Limiting < ±5%, internal Leading Edge Blanking, and user-defined Soft Start. Additionally, it features soft driving for low EMI.
Application Scenarios
The 2A0565 IC chips are used in various industrial power applications that require low power standby, overload protection & open-loop protection. They are especially suitable for applications that require a stable output voltage in standby mode, such as in the telecommunications, networking, and computer industries. These IC chips are also commonly used in LED lighting, power supplies, and adapters.
Comparison
Advantages- More cost-effective for the overall system due to the internal precise peak current limitation, and lower-sized transformer and secondary diode.
- No heat-sink required for DIP8, DIP7, and DSO16/12 packages.
- Increased creepage distance for TO220, DIP7, and DSO16/12.
- Lowest standby power dissipation and lowest total BOM cost
Disadvantages- The 2A0565 requires a precise adjustment of the external resistor for optimal performance, which could be a challenge for some users.
- The frequency reduction in standby mode of 20kHz/21.5 kHz to avoid audible noise may not be ideal for applications that require high-frequency operation, such as video and audio equipment.
- The device's maximum duty cycle of 72% may not be sufficient for some high-power applications.
