ICE3PCS01GXUMA1

ICE3PCS01GXUMA1 is a standalone power factor correction controller in continuous conduction mode. It is a 14-pin wide input range controller IC for active power factor correction converters. It is designed for converters in boost topology and requires few external components. Its power supply is recommended to be provided by an external auxiliary supply which will switch on and off the IC.

• High efficiency over the whole load range, lowest count of external components
• Accurate and adjustable switching frequency, separate signal and power ground pins
• Bulk voltage good signal for inrush relay control or PWM IC enabling
• Integrated digital voltage loop compensation, fast output dynamic response during load jump
• External synchronization, extra low peak current limitation, maximum duty cycle of 95% (typical)
• Continuous current operation mode PFC, enhanced dynamic response without input current distortion
• Programmable boost follower step level according to input line and output power conditions
• Accurate brown-out protection threshold, external current loop compensation greater user flexibility
• Open loop protection, second over bulk voltage protection, PFC enable function
• PG-DSO-14 package, -40 to 150°C junction temperature
