ICE2QR4780G

ICE2QR4780G Quasi-Resonant, 800V CoolSET™ in DS0-12 Package Product Highlights  Active Burst Mode to reach the lowest standby power requirement 25 V & last for 10 μs (normal mode only) VCC Undervoltage/ Short Optocoupler VVCC < 10.5 V Auto Restart Overload/Open Loop VFB > 4.5 V & last for 30 ms Auto Restart Over Temperature (Controller Junction) TJ > 140 °C Auto Restart Output Overvoltage VZCOVP > 3.7 V & last for 100 μs Latch Short Winding VCSSW > 1.68 V & last for 190 ns Latch In case of open control loop or output over load, the feedback voltage will be pulled up. After a blanking time of tOLP_B (30 ms), the IC enters auto-restart mode. The blanking time here enables the converter to provide a peak power in case the increase in VFB is due to a sudden load increase. This output over load protection is disabled during burst mode. During off-time of the power switch, the voltage at the zero-crossing pin is monitored for output over-voltage detection. If the voltage is higher than the preset threshold VZCOVP, the IC is latched off after the preset blanking time tZCOVP. This latch off mode can only be reset if the VVCC < VVCCPD. If the junction temperature of IC controller exceeds TjCon (130 °C), the IC enters into OTP auto restart mode. This OTP is disabled during burst mode. If the voltage at the current sensing pin is higher than the preset threshold VCSSW during on-time of the power switch, the IC is latched off. This is short-winding protection. The short winding protection is disabled during burst mode. During latch-off protection mode, the VCC voltage drops to VVCCoff (10.5 V) and then the startup cell is activated. The VCC voltage is then charged to VVCCon (18 V). The startup cell is shut down again. This action repeats again and again. There is also a maximum on time limitation implemented inside the CoolSET™ Q1. Once the gate voltage is high and longer than tOnMax, the switch is turned off immediately.

The voltage levels are valid if other ratings are not violated. Absolute Maximum Ratings Absolute maximum ratings are defined as ratings, which when being exceeded may lead to destruction of the integrated circuit. For the same reason make sure, that any capacitor that will be connected to pin 11 (VCC) is discharged before assembling the application circuit.

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 232 mm2 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 13), operating temperature is 50°C, estimated efficiency is 85%, then the estimated output power is 18.7 W (22 W * 85%).
