2B0565 PDF Datasheet – 650V, MOS Transistor, ICE2B0565

Part Number: 2B0565, ICE2B0565

Function: 650V, Off-Line SMPS Current Mode Controller

Package: DIP 8 Pin Type

Manufacturer: Infineon Technologies




The 2B0565 is 650V, Off-Line SMPS Current Mode Controller with integrated 650V CoolMOS Power Management & Supply. A Switched-Mode Power Supply (SMPS) Current Mode Controller is a critical component in the control circuitry of a switching power supply. It is responsible for regulating the output voltage by monitoring and controlling the current flowing through the power supply’s switching elements (typically transistors or MOSFETs) to maintain stable and efficient operation.

The second generation CoolSET-F2 provides several special enhancements to satisfy the needs for low power standby and protection features. In standby mode frequency reduction is used to lower the power consumption and support a stable output voltage in this mode. The frequency reduction is limited to 20kHz/21.5 kHz to avoid audible noise. In case of failure modes like
open loop, overvoltage or overload due to short circuit the device switches in Auto Restart Mode which is controlled by the internal protection unit.
