ICE3PCS01G

VCC CCM-PFC ICE3PCS01G Standalone Power Factor Correction (PFC) Controller in Continuous Conduction Mode (CCM) Product Highlights 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 ICE3PCS01G Fast output dynamic response during load jump PG-DSO-14 External synchronization Extra low peak current limitation Features Description Continuous current operation mode PFC The ICE3PCS01G is a 14-pins wide input range controller Wide input range of Vcc up to 25V IC for active power factor correction converters. It is de- Programmable boost follower step level according signed for converters in boost topology, and requires few to input line and output power conditions external components. Its power supply is recommended to Enhanced dynamic response without input current be provided by an external auxiliary supply which will distortion switch on and off the IC. Accurate brown-out protection threshold External current loop compensation for greater user flexibility Open loop protection Second over bulk voltage protection PFC enable function Separate signal and power ground pins Maximum duty cycle of 95% (typical) DBYP R NTC D B L Boos t V CC R R R GATE BVS 1 BVS 4 Line CB 90 ~ 270 Vac Filter C E RGS R RBVS 2 BVS 5 RSHUNT R R BVS 3 BVS 6 DBRO1 DBRO2 R CS Qrel RRel R BRO1 VB OK ISENSE GATE PGND VSENSE OVP PWM RBRO2 Feedback BOP RBOFO 1 BOFO RBRO3 C BRO VREF SGND VBTHL EN FREQ ICOMP VCC R BOFO 2 R VB 1 RVB 2 R C C FREQ ICOMP VCC Type Package ICE3PCS01G PG-DSO-14 Version 3.0 1 03 April 2017CCM-PFC ICE3PCS01G 1 Pin Configuration and Functionality .4 1.1 Pin Configuration 4 1.2 Pin Functionality 4 2 Block Diagram .6 3 Functional Description 8 3.1 General .8 3.2 Power Supply .8 3.3 Start-up .8 3.4 Frequency Setting and External Synchronization .8 3.4.1 Frequency Setting .8 3.4.2 External Synchronization 9 3.5 Voltage Loop .9 3.5.1 Notch Filter 9 3.5.2 Voltage Loop Compensation .9 3.6 Average Current Control .10 3.6.1 Complete Current Loop 10 3.6.2 Current Loop Compensation 10 3.6.3 Pulse Width Modulation (PWM) 10 3.7 PWM Logic .11 3.8 System Protection 11 3.8.1 Input Voltage Brownout Protection(BOP) 11 3.8.2 Peak Current Limit (PCL) .12 3.8.3 Open Loop Protection (OLP) 12 3.8.4 First Over-Voltage Protection (OVP1) .12 3.8.5 Second Over Voltage Protection (OVP2) 12 3.8.6 Bulk Voltage Monitor and Enable Function .12 3.8.7 Boost Follower .12 3.9 Output Gate Driver 13 3.10 Protection Function .14 4 Electrical Characteristics .15 4.1 Absolute Maximum Ratings .15 4.2 Operating Range .16 4.3 Characteristics .16 4.3.1 Supply Section .16 4.3.2 Variable Frequency Section .17 4.3.3 PWM Section 17 4.3.4 External Synchronization .17 4.3.5 PFC Brownout Protection Section 18 4.3.6 System Protection Section 18 4.3.7 Internal Voltage Reference .18 4.3.8 Boost Follower Section 19 Version 3.0 2 03 April 2017
