Since there is no more switching, the VCC voltage will drop. When it hits the Vcc turn off threshold, the start up cell will turn on and the Vcc is charged by the startup cell current to VCC turn on threshold. The IC is on and the startup cell will turn off. At this stage, it will enter the startup phase (soft start) with switching cycles. After the Start Up Phase, the fault condition is checked. If the fault condition persists, the IC will go to auto restart mode again. If, otherwise, the fault is removed, normal operation is resumed. 3.7.3.1 Auto Restart mode with extended blanking time 5.0V IBK BA Auto Restart Mode C3 # CBK 4.0V 0.9V & 1 S1 G2 4.0V FB G5 C4 Spike Blanking 8.0us 20ms Blanking Time Control Unit Figure 26 Auto Restart Mode In case of Overload or Open Loop, the FB exceeds 4.0 V which will be observed by comparator C4. Then the internal blanking counter starts to count. When it reaches 20 ms, the switch S1 is released. Then the clamped voltage 0.9 V at VBA can increase. When there is no external capacitor CBK connected, the VBA will reach 4.0 V immediately. When both the input signals at AND gate G5 is positive, the Auto Restart Mode will be activated after the extra spike blanking time of 30 µs is elapsed. However, when an extra blanking time is needed, it can be Data Sheet 18 Revision 1.1 2017-06-13 Fixed-Frequency, 650V CoolSET™ in DS0-12 Package Functional Description achieved by adding an external capacitor, CBK. A constant current source of IBK will start to charge the capacitor CBK from 0.9 V to 4.0 V after the switch S1 is released. The charging time from 0.9 V to 4.0 V are the extendable blanking time. If CBK is 0.22 µF and IBK is 13 µA, the extendable blanking time is around 52 ms and the total blanking time is 72 ms. In combining the FB and blanking time, there is a blanking window generated which prevents the system to enter Auto Restart Mode due to large load jumps. 3.7.3.2 Auto Restart mode without extended blanking time 1ms counter Auto-restart Enable Signal UVLO BA 0.33V Stop gate drive 8us Blanking Time C9 Auto Restart mode 25.5V TAE VCC Auto Restart Mode Reset VVCC < 10.5V 120us Blanking Time C2 softs_period & VCC C1 Spike Blanking 30us G1 20.5V Voltage Reference 4.0V C4 FB Thermal Shutdown Tj >130°C Control Unit Figure 27 Over load, open loop protection There are 2 modes of VCC overvoltage protection; one is during soft start and the other is at all conditions. The first one is VVCC voltage is > 20.5 V and FB is > 4.0 V and during soft start period and the IC enters Auto Restart Mode. The VCC voltage is observed by comparator C1 and C4. The fault conditions are to detect the abnormal operating during start up such as open loop during light load start up, etc. The logic can eliminate the possible of entering Auto Restart mode if there is a small voltage overshoots of VVCC during normal operating. The 2nd one is VVCC >25.5 V and last for 120 µs and the IC enters Auto Restart Mode. This 25.5 V VCC OVP protection is inactivated during burst mode. The Thermal Shutdown block monitors the junction temperature of the IC. After detecting a junction temperature higher than 130 °C, the Auto Restart Mode is entered. In case the pre-defined auto-restart features are not sufficient, there is a customer defined external Auto-restart Enable feature. This function can be triggered by pulling down the BA pin to < 0.33 V. It can simply add a trigger signal to the base of the externally added transistor, TAE at the BA pin. When the function is enabled, the gate drive switching will be stopped and then the IC will enter auto-restart mode if the signal persists. To ensure this auto-restart function will not be mis-triggered during start up, a 1 ms delay time is implemented to blank the unstable signal. VCC undervoltage is the VCC voltage drop below Vcc turn off threshold. Then the IC will turn off and the start up cell will turn on automatically. And this leads to Auto Restart Mode. Short Optocoupler also leads to VCC undervoltage as there is no self supply after activating the internal reference and bias.

The curves are derived based on a typical discontinuous mode flyback model which considers either 50% maximum duty ratio or 100 V maximum secondary to primary reflected voltage (higher priority). The calculation is based on no copper area as heatsink for the device. The input power already includes the power loss at input common mode choke, bridge rectifier and the CoolMOS™.The device saturation current (ID_Puls @ Tj=125°C) is also considered. To estimate the output power of the device, it is simply multiplying the input power at a particular operating ambient temperature with the estimated efficiency for the application. For example, a wide range input voltage (Figure 32), operating temperature is 50°C, estimated efficiency is 85%, then the estimated output power is 37 W (43.83 W x 85%).

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. 400 V traces (positive rail of bulk capacitor C11) to nearby trace: > 2.0 mm b. 600 V traces (drain voltage of CoolSET™ IC11) to nearby trace: > 2.5 mm 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 > 3 kV lightning surge test applied (Figure 36) 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. Data Sheet 30 Revision 1.1 2017-06-13 Fixed-Frequency, 650V CoolSET™ in DS0-12 Package Schematic for recommended PCB layout a. Spark Gap 3 and Spark Gap 4, input common mode choke, L1: Gap separation is around 1.5 mm (no safety concern) 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 > 6 kV. 230 VAC input voltage application, the gap separation is around 5.5mm 115 VAC 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 1N4148. 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.
