By use of a BiCMOS technology a wide VCC range up to 26V is provided. This covers the changes in the auxiliary supply voltage if a CV/CC regulation is implemented on the secondary side. Furthermore an Active Burst Mode is integrated to fullfill the lowest Standby Power Requirements 4.5V. Therefore the overvoltage detection can only be active during Soft Start Phase (VSoftS < 4.0V) and when FB signal is outside the operating range > 4.5V. This means any t Figure 15 Control Unit Signals in Active Burst Mode 13 25 Mar 2013 CoolSET®-F3 ICE3Bxx65J small voltage overshoots of VVCC during normal operating cannot trigger the Auto Restart Mode I. In Order to ensure system reliability and prevent any false activation, a blanking time is implemented before the IC can enter into the Auto Restart Mode I. The output of the VCC overvoltage detection is fed into a spike blanking with a time constant of 8.0us. The other fault detection which can result in the Auto Restart Mode I and has this 8.0us blanking time is the Overtemperature detection. This block checks for a junction temperature of higher than 140°C for malfunction operation. Once Auto Restart Mode is entered, the internal bias is switched off in order to reduce the current consumption of the IC as much as possible. In this mode, the average current consumption is only 300uA as the only working blocks are the reference block and the Undervoltage Lockout(UVLO) which controls the Startup Cell by switching on/off at V VCCon/VVCCoff. As there is no longer a self supply by the auxiliary winding, VCC starts to drop. The UVLO switches on the integrated Startup Cell when VCC falls below 10.3V. It will continue to charge VCC up to 18V whereby it is switched off again and the IC enters into the Start Up Phase. As long as all fault conditions have been removed, the IC will automatically power up as usual with switching cycle at the GATE output after Soft Start duration. Thus the name Auto Restart Mode. 3.6.3.2 This charging of the Soft Start capacitor from 3.2V~3.6V to 4.0V defines a blanking window which prevents the system from entering into Auto Restart Mode II unintentionally during large load jumps. In this event, FB will rise close to 5.0V for a short duration before the loop regulates with FB less than 4.5V. This is the same blanking time window as for the Active Burst Mode and can therefore be adjusted by the external CSoftS. In case of VCC undervoltage, ie. VCC falls below 10.3V, the IC will be turned off with the Startup Cell charging VCC as described earlier in this section. Once VCC is charged above 18V, the IC will start a new startup cycle. The same procedure applies when the system is under Short Optocoupler fault condition, as it will lead to VCC undervoltage. Auto Restart Mode II Internal Bias SoftS C3 4.0V & 4.5V C4 G5 Auto Restart Mode FB Control Unit Figure 17 Auto Restart Mode II In case of Overload or Open Loop, FB exceeds 4.5V which will be observed by C4. At this time, the external Soft Start capacitor can now be charged further by the integrated pull up resistor R SoftS via switch S3 (see Figure 13). If V SoftS exceeds 4.0V which is observed by C3, Auto Restart Mode II is entered as both inputs of the gate G5 are high.

It can reduce the switching noise going into the sensitive pins of the CoolSET device effectively. The primary DC grounds include the followings. a. DC ground of the primary auxiliary winding in power transformer, TR1, and ground of C16 and Z11. b. DC ground of the current sense resistor, R12 c. DC ground of the CoolSET device, GND pin of IC11; the signal grounds from C13, C14, C15 and collector of IC12 should be connected to the GND pin of IC11 and then “star “connect to the bulk capacitor ground. d. DC ground from bridge rectifier, BR1 e. DC ground from the bridging Y-capacitor, C4 2. High voltage traces clearance: High voltage traces should keep enough spacing to the nearby traces. Otherwise, arcing would incur. a. 400V traces (positive rail of bulk capacitor C11) to nearby trace: > 2.0mm b. 600V traces (drain voltage of CoolSET IC11) to nearby trace: > 2.5mm 3. Filter capacitor close to the controller ground: Filter capacitors, C13, C14 and C15 should be placed as close to the controller ground and the controller pin as possible so as to reduce the switching noise coupled into the controller. Guideline for PCB layout design when >3KV lightning surge test applied (refer to Figure 26): 1. Add spark gap Spark gap is a pair of saw-tooth like copper plate facing each other which can discharge the accumulated charge during surge test through the sharp point of the saw-tooth plate. a. Spark Gap 3 and Spark Gap 4, input common mode choke, L1: Gap separation is around 1.5mm (no safety concern) Version 2.9 26 25 Mar 2013 CoolSET®-F3 ICE3Bxx65J Schematic for recommended PCB layout b. Spark Gap 1 and Spark Gap 2, Live / Neutral to GROUND: These 2 Spark Gaps can be used when the lightning surge requirement is >6KV. 230Vac input voltage application, the gap separation is around 5.5mm 115Vac input voltage application, the gap separation is around 3mm 2. Add Y-capacitor (C2 and C3) in the Live and Neutral to ground even though it is a 2-pin input 3. Add negative pulse clamping diode, D11 to the Current sense resistor, R12: The negative pulse clamping diode can reduce the negative pulse going into the CS pin of the CoolSET and reduce the abnormal behavior of the CoolSET. The diode can be a fast speed diode such as IN4148. The principle behind is to drain the high surge voltage from Live/Neutral to Ground without passing through the sensitive components such as the primary controller, IC11.
