ICE2PCS02G中文资料AC-DC PWM-PFC 控制器数据手册Infineon规格书

描述 Description

ICE2PCS0x/G are the 2nd generation of Continuous Conduction Mode (CCM) PFC controllers, which employ BiCMOS technology. Compared to the 1 st generation of ICE1PCS01/02, the new ICs have lower internal reference trimmed at 3V. They also have other advantages such as wider Vcc operating range, improved internal oscillator and additional direct bulk capacitor over-voltage protection.

特性 Features

• Supports Wide Range

• Average Current Control

• External Current and Voltage Loop Compensation for Greater User Flexibility

• Programmable Operating/Switching Frequency (50kHz - 250kHz)

• Max Duty Cycle of 95% (at 25°C) at 125kHz

• Trimmed Internal Reference Voltage (3V+2% at 25°C)

• VCC Under-Voltage Lockout

• Cycle by Cycle Peak Current Limiting

• Output Over-Voltage Protection

• Open Loop Detection

• Enhanced Dynamic Response
