CCM-PFC ICE2PCS01/G Functional Description 3 Functional Description 3.1 General If VCC drops below 11V, the IC is off. The IC will then be consuming typically 300mA, whereas consuming 13mA during normal operation. The IC can be turned off and forced into standby mode by pulling down the voltage at pin 6 (VSENSE) to lower than 0.6V. The current consumption is reduced to 300µA in this mode. The ICE2PCS01/G is a 8 pin control IC for power factor correction converters.
CCM-PFC ICE2PCS01/G Functional Description 3.4 Window Detect The IC provides several protection features in order to ensure the PFC system in safe operating range. Depending on the input line voltage (VIN) and output bus voltage (VOUT), Figure 7 and 8 show the conditions when these protections are active.
CCM-PFC ICE2PCS01/G Functional Description POUT(rated) IC’s State connected) or an insufficient input voltage VIN for normal operation. In this case, most of the blocks within the IC will be shutdown. It is implemented using comparator C3 with a threshold of 0.6V as shown in the IC block diagram in Figure 2. POUT(max) Normal Operation SOC 3.4.4 Over-Voltage Protection (OVP) Whenever VOUT exceeds the rated value by 5%, the over-voltage protection OVP is active as shown in Figure 6.
CCM-PFC ICE2PCS01/G Functional Description 3.6 Average Current Control From the above equation, DOFF is proportional to VIN. The objective of the current loop is to regulate the average inductor current such that it is proportional to the off duty cycle DOFF, and thus to the input voltage VIN. Figure 12 shows the scheme to achieve the objective. 3.6.1 Complete Current Loop The complete system current loop is shown in Figure 11.
CCM-PFC ICE2PCS01/G Functional Description voltage at pin VCOMP. This block has been designed to support the wide input voltage range (85-265VAC). 3.7 From Full-wave Retifier PWM Logic The PWM logic block prioritizes the control input signals and generates the final logic signal to turn on the driver stage. The speed of the logic gates in this block, together with the width of the reset pulse TOFFMIN, are designed to meet a maximum duty cycle DMAX of 95% at the GATE output under 136kHz of operation.
