ICE3PCS01GXUMA1

ICE3PCS01GXUMA1 is a standalone power factor correction (PFC) controller in continuous conduction mode (CCM). The CE3PCS01G is the new 14-pin wide input range (85V AC to 265V AC) controller IC for active CCM power factor correction converter. Compared to the 1st, 2nd generation of ICE1PCS0x and ICE2PCS0x, the 3rd generation PFC has lowest internal reference trimmed at 2.5V and integrated digital control voltage loop. They also have other advantages such as low peak current limit at 0.2V, adjustable gate switching frequency range from 21kHz to 100kHz and able to synchronize with external frequency range from 50kHz to 100kHz. They are now able to achieve 95% efficiency at full load for all input voltage range. It features continuous current operation mode PFC, wide input range of VCC up to 25V, programmable boost follower step level according to input line and output power conditions, enhanced dynamic response without input current distortion and accurate brown-out protection threshold.

• High efficiency over the whole load range
• Lowest count of external components
• Accurate and adjustable switching frequency
• 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 and extra low peak current limitation
• Open loop protection, second over bulk voltage protection and PFC enable function
• External current loop compensation for greater user flexibility
• 14 pin SOIC package
