VIPER06 Energy saving high voltage converter for direct feedback Datasheet - production data Applications     Replacement of capacitive power supplies Home appliances Power metering LED drivers Description The VIPER06 is an offline converter with an 800 V avalanche rugged power section, a PWM controller, a user-defined overcurrent limit, open-loop failure protection, hysteretic thermal protection, soft startup and safe auto-restart after any fault condition. The device is able to power itself directly from the rectified mains, eliminating the need for an auxiliary bias winding. Advanced frequency jittering reduces EMI filter cost. Burst mode operation and the device’s very low power consumption both help to meet the standards set by energy-saving regulations.

It includes a SenseFET structure to allow virtually lossless current sensing and the thermal sensor. The gate driver of the power MOSFET is designed to supply a controlled gate current during both turn-ON and turn-OFF in order to minimize common-mode EMI. During UVLO conditions, an internal pull-down circuit holds the gate low in order to ensure that the power MOSFET cannot be turned ON accidentally. 8 High voltage current generator The high-voltage current generator is supplied by the DRAIN pin. At the first startup of the converter it is enabled when the voltage across the input bulk capacitor reaches the VDRAIN_START threshold, sourcing a IDDch1 current (see Table 6: "Supply section "). As the VDD voltage reaches the VDDon threshold, the power section starts switching and the highvoltage current generator is turned OFF. The VIPER06 is powered by the energy stored in the VDD capacitor. In a steady-state condition, if the self-biasing function is used, the high-voltage current generator is activated between VDDCSon and VDDon (see Table 6: "Supply section "), delivering IDDch2, see Table 6: "Supply section " to the VDD capacitor during the MOSFET off-time (see Figure 22: "Power-on and power-off"). The device can also be supplied through the auxiliary winding in which case the highvoltage current source is disabled during steady-state operation, provided that VDD is above VDDCSon. At converter power-down, the VDD voltage drops and the converter activity stops as it falls below the VDDoff threshold (see Table 6: "Supply section "). Figure 22: Power-on and power-off 14/28 DocID022794 Rev 2 VIPER06 9 Oscillator Oscillator The switching frequency is internally fixed at 30 kHz or 60 kHz or 115 kHz (respectively part numbers VIPER06Xx, VIPER06Lx and VIPER06Hx). The switching frequency is modulated by approximately ±3 kHz (30 kHz version) or ±4 kHz (60 kHz version) or ±8 kHz (115 kHz version) at 230 Hz (typical) rate, so that the resulting spread spectrum action distributes the energy of each harmonic of the switching frequency over a number of sideband harmonics having the same energy on the whole, but smaller amplitudes. 10 Soft startup During the converter’s startup phase, the soft-start function progressively increases the cycle-by-cycle drain current limit, up to the default value IDlim. In this way the drain current is further limited and the output voltage is progressively increased, reducing the stress on the secondary diode. The soft-start time is internally fixed to tSS, see typical value in Table 7: "Controller section ", and the function is activated for any attempt of converter startup and after a fault event. This function helps prevent saturation of the transformer during startup and short-circuit. 11 Adjustable current limit set point The VIPER06 includes a current-mode PWM controller. The drain current is sensed cycleby-cycle through the integrated resistor RSENSE and the voltage is applied to the noninverting input of the PWM comparator, see Figure 2: "Block diagram". As soon as the sensed voltage is equal to the voltage derived from the COMP pin, the power MOSFET is switched OFF. In parallel with the PWM operations, the comparator OCP, see Figure 2: "Block diagram", checks the level of the drain current and switches OFF the power MOSFET in case the current is higher than the threshold IDlim, see Table 7: "Controller section ". The level of the drain current limit IDlim can be reduced using a resistor RLIM connected between the LIM and GND pins. Current is sunk from the LIM pin through the resistor RLIM and the setup of IDlim depends on the level of this current. The relation between I Dlim and RLIM is shown in Figure 14: "IDlim vs RLIM". When the LIM pin is left open or if RLIM has a high value (i.e. > 80 kΩ), the current limit is fixed to its default value, IDlim, as given in Table 7: "Controller section ". DocID022794 Rev 2 15/28 FB pin and COMP pin 12 VIPER06 FB pin and COMP pin The device can be used both in non-isolated and isolated topology. In non-isolated topology, the feedback signal from the output voltage is applied directly to the FB pin as the inverting input of the internal error amplifier having the reference voltage, V REF_FB, see Table 7: "Controller section ". The output of the error amplifier sources and sinks the current, ICOMP, respectively to and from the compensation network connected on the COMP pin. This signal is then compared in the PWM comparator with the signal coming from the SenseFET in order to switch off the power MOSFET on a cycle-by-cycle basis. See the Figure 2: "Block diagram" and the Figure 23: "Feedback circuit". When the power supply output voltage is equal to the error amplifier reference voltage, VREF_FB, a single resistor has to be connected from the output to the FB pin. For higher output voltages the external resistor divider is needed. If the voltage on the FB pin is accidentally left floating, an internal pull-up protects the controller. The output of the error amplifier is externally accessible through the COMP pin and it’s used for the loop compensation, usually an RC network. As shown in Figure 23: "Feedback circuit", in case of an isolated power supply, the internal error amplifier has to be disabled (FB pin shorted to GND). In this case an internal resistor is connected between an internal reference voltage and the COMP pin, see Figure 23: "Feedback circuit". The current loop has to be closed on the COMP pin through the optotransistor in parallel with the compensation network. The V COMP dynamic range is between VCOMPL and VCOMPH shown in Figure 24: "COMP pin voltage versus IDRAIN". When the voltage VCOMP drops below the voltage threshold VCOMPL, the converter enters burst mode, see Section 13: "Burst mode". When the voltage VCOMP rises above the VCOMPH threshold, the peak drain current, as well as the deliverable output power, will reach its limit. Figure 23: Feedback circuit 16/28 DocID022794 Rev 2 VIPER06 Burst mode Figure 24: COMP pin voltage versus IDRAIN 13 Burst mode When the voltage VCOMP drops below the threshold, VCOMPL, the power MOSFET is kept in the OFF state and the consumption is reduced to the IDD0 current, as reported on Table 6: "Supply section ". In reaction to the loss of energy, the VCOMP voltage increases and as soon as it exceeds the threshold VCOMPL + VCOMPL_HYS, the converter starts switching again with a level of consumption equal to the IDD1 current. This ON-OFF operation mode, referred to as “burst mode” and shown in Figure 25: "Load-dependent operating modes: timing waveforms", reduces the average frequency, which can go down even to a few hundreds hertz, thus minimizing all frequency-related losses and making it easier to comply with energy-saving regulations. During burst mode, the drain current limit is reduced to the value IDlim_bm (given in Table 7: "Controller section ") in order to avoid the audible noise issue. Figure 25: Load-dependent operating modes: timing waveforms DocID022794 Rev 2 17/28 Automatic auto-restart after overload or shortcircuit 14 VIPER06 Automatic auto-restart after overload or short-circuit The overload protection is implemented automatically using the integrated up-down counter. Every cycle, it is incremented or decremented depending upon the current logic detection of the limit condition or not. The limit condition is the peak drain current, IDlim , given in Table 7: "Controller section " or the one set by the user through the RLIM resistor, shown in Figure 14: "IDlim vs RLIM". After the reset of the counter, if the peak drain current is continuously equal to the level IDlim, the counter will be incremented until the fixed time, tOVL, at which point the power MOSFET switch ON will be disabled. It will be activated again through the soft-start after the tRESTART time (see Figure 26: "Timing diagram: OLP sequence (IC externally biased)" and Figure 27: "Timing diagram: OLP sequence (IC internally biased)") and the time values mentioned in Table 7: "Controller section ". For overload or short-circuit events, the power MOSFET switching will be stopped after a period of time dependent upon the counter with a maximum equal to t OVL. The protection sequence continues until the overload condition is removed, see Figure 26: "Timing diagram: OLP sequence (IC externally biased)" and Figure 27: "Timing diagram: OLP sequence (IC internally biased)". This protection ensures a low repetition rate of restart attempts of the converter, so that it works safely with extremely low power throughput and avoids overheating the IC in case of repeated overload events. If the overload is removed before the protection tripping, the counter will be decremented cycle-by-cycle down to zero and the IC will not be stopped. Figure 26: Timing diagram: OLP sequence (IC externally biased) Figure 27: Timing diagram: OLP sequence (IC internally biased) 18/28 DocID022794 Rev 2 VIPER06 15 Open-loop failure protection Open-loop failure protection If the power supply has been designed using flyback topology and the VIPER06 is supplied by an auxiliary winding, as shown in Figure 28: "FB pin connection for non-isolated flyback" and Figure 29: "FB pin connection for isolated flyback", the converter is protected against feedback loop failure or accidental disconnections of the winding. The following description is applicable for the schematics of Figure 28: "FB pin connection for non-isolated flyback" and Figure 29: "FB pin connection for isolated flyback", respectively the non-isolated flyback and the isolated flyback. If RH is open or RL is shorted, the VIPER06 works at its drain current limitation. The output voltage, VOUT, will increase as does the auxiliary voltage, VAUX, which is coupled with the output through the secondary-to-auxiliary turns ratio. As the auxiliary voltage increases up to the internal VDD active clamp, VDDclamp (the value is given in Table 7: "Controller section ") and the clamp current injected on the VDD pin exceeds the latch threshold, IDDol (the value is given in Table 7: "Controller section "), a fault signal is internally generated. In order to distinguish an actual malfunction from a bad auxiliary winding design, both the above conditions (drain current equal to the drain current limitation and current higher than IDDol through the VDD clamp) have to be verified to reveal the fault. If RL is open or RH is shorted, the output voltage, VOUT, will be clamped to the reference voltage VREF_FB (for non-isolated flyback) or to the external TL voltage reference (for isolated flyback). Figure 28: FB pin connection for non-isolated flyback DocID022794 Rev 2 19/28 Layout guidelines and design recommendations VIPER06 Figure 29: FB pin connection for isolated flyback 16 Layout guidelines and design recommendations A proper printed circuit board layout is essential for correct operation of any switch-mode converter and this is true for the VIPer06 as well. Also some trick can be used to make the design rugged versus external influences. Careful component placing, correct traces routing, appropriate traces widths and compliance with isolation distances are the major issues. The main reasons to have a proper PCB routing are:   Provide a noise free path for the signal ground and for the internal references, ensuring good immunity against switching noises Minimize the pulsed loops (both primary and secondary) to reduce the electromagnetic interferences, both radiated and conducted and passing more easily the EMC regulations. The below list can be used as guideline when designing a SMPS using VIPer06.     20/28 Signal ground routing should be routed separately from power ground and, in general, from any pulsed high current loop; Connect all the signal ground traces to the power ground, using a single "star point", placed close to the IC GND pin; With flyback topologies, when the auxiliary winding is used, it is suggested to connect the VDD capacitor on the auxiliary return and then to the main GND using a single track; The compensation network should be connected as close as possible to the COMP pin, maintaining the trace for the GND as short as possible; DocID022794 Rev 2 VIPER06 Layout guidelines and design recommendations      A small bypass capacitor (a few hundreds pF up to 0.1 µF) to GND might be useful to get a clean bias voltage for the signal part of the IC and protect the IC itself during EFT/ESD tests. A low ESL ceramic capacitor should be used, placed as close as possible to the VDD pin; When using SO16N package it is recommended to connect the pin 4 to GND pin, using a signal track, in order to improve the noise immunity. This is highly recommended in case of high nosily environment; The IC thermal dissipation takes place through the drain pins. An adequate heat sink copper area has to be designed under the drain pins to improve the thermal dissipation; It is not recommended to place large copper areas on the GND pins. Minimize the area of the pulsed loops (primary, RCD and secondary loops), in order to reduce its parasitic self- inductance and the radiated electromagnetic field: this will greatly reduce the electromagnetic interferences produced by the power supply during the switching.
