概述
Description
The ICE2A265 is an integrated circuit (IC) designed for switch-mode power supply (SMPS) applications, particularly as a current-mode PWM controller. Key features include:
- Current-mode control for stable operation.
- Fixed switching frequency (typically 100 kHz).
- Built-in soft-start and overload protection.
- Low standby power consumption.
- High-voltage startup (up to 800V).
It is commonly used in offline power supplies, such as adapters, LED drivers, and auxiliary power units. The IC simplifies design by integrating critical functions like PWM generation, feedback control, and protection circuits, reducing external component count.
For detailed specifications, refer to the Infineon datasheet (or relevant manufacturer documentation).
