NCL30059 High-Voltage Half-Bridge Controller for LED Lighting Applications The NCL30059 is a self−oscillating high voltage MOSFET driver primarily tailored for LED driver applications using half−bridge topology. LLC and LCC configurations are supported with optimized wide range control offered by the latter for Constant Current (CC) applications. Due to its proprietary 600 V technology, the driver is useful for bulk voltages utilized in 277 VAC lighting applications. Operating frequency of the driver can be adjusted from 25 kHz to 250 kHz using a single resistor. Adjustable brown−out protection assures correct bulk voltage operating range. An internal 100 ms PFC delay timer ensures the converter is enabled after the bulk voltage is fully stabilized. The device provides fixed dead−time which helps to lower the shoot−through current.

It supports LLC and optimized LCC topologies offering wide output voltage range in constant current (CC) mode making it ideal for LED drivers. The IC includes several features that help the designer to cope with resonant SPMS design. All features are described thereafter: • Wide Operating Frequency Range: The internal current controlled oscillator is capable to operate over wide frequency range up to 250 kHz. Minimum frequency accuracy is $3%. • Fixed Dead−Time: Internal dead−time control is optimized to avoid cross conduction or shoot−through during transitions between low and high side conduction. • 100 ms PFC Timer: Fixed delay is placed to IC operation whenever the driver restarts (VCCON or BO_OK detect events). This delay assures that the bulk voltage will be stabilized prior to switching operation. Another benefit of this delay is that the soft start capacitor will be fully discharged before any restart. • Brown−Out Detection: The BO input monitors bulk voltage level via resistor divider and thus assures that the application is working only for wanted bulk voltage band. The BO input sinks current of 18.2 mA until the VrefBO threshold is reached. Designer can thus adjust the bulk voltage hysteresis according to the application needs. • • connected in parallel to the BO terminal to allow the designer latch the IC if necessary − overvoltage or overtemperature shutdown can be implemented using this latch. The supply voltage has to be cycled down below VCCreset threshold, or VBO diminished under VBO level to reset the latch and enable restart. Internal VCC Clamp: The internal zener clamp offers a way to prepare passive voltage regulator to maintain VCC voltage at 16 V in case the controller is supplied from unregulated power supply or from bulk capacitor. Low Startup Current: This device features maximum startup current of 50 mA which allows the designer to use high value startup resistor for applications when driver is supplied from the auxiliary winding. Power dissipation of startup resistor is thus significantly reduced. Current Controlled Oscillator The current controlled oscillator features a high−speed circuitry allowing operation from 50 kHz up to 500 kHz. However, as a division by two internally creates the two Q and Q outputs, the final effective signal on output Mlower and Mupper switches between 25 kHz and 250 kHz. The VCO is configured in such a way that if the current that flows out from the Rt pin increases, the switching frequency also goes up. Figure 21 shows the architecture of this oscillator.

The Internal Current Controlled Oscillator Architecture www.onsemi.com 9 NCL30059 This is valuable for applications that are supplied from auxiliary winding and VCC capacitor is supposed to provide energy during PFC delay period. For resonant LED driver applications it is necessary to adjust minimum operating frequency with high accuracy. The designer also needs to limit maximum operating and startup frequency. All these parameters can be adjusted using few external components connected to the Rt pin as depicted in Figure 22. The internal timing capacitor Ct is charged by current which is proportional to the current flowing out from the Rt pin. The discharging current IDT is applied when voltage on this capacitor reaches 2.5 V. The output drivers are disabled during discharge period so the dead time length is given by the discharge current sink capability. Discharge sink is disabled when voltage on the timing capacitor reaches zero and charging cycle starts again. The charging current and thus also whole oscillator is disabled during the PFC delay period to keep the IC consumption below 400 mA. NCL30059 Rt V CC Rfmax Rfmax−CC Rbias Rfstart D1 Rt Rcomp (to secondary voltage regulator) Ccomp CSS TLV431 Voltage Feedback (to primary current sensor) Current Feedback Figure 22. Typical Rt Pin Connection regulator. This voltage difference is applied across Rfmax−CC. The TLV431 shunt regulator is used in Figure 22 as the constant current control regulator. Diode D1 is used to establish minimum regulator bias current via resistor Rbias. Total saturation voltage of this solution is 1.25 + 0.6 = 1.85 V for room temperature. Shottky diode will further decrease saturation voltage. The Rfmax−CC resistor limits the maximum frequency delivered by this regulation loop. This parameter is affected by D1 temperature drift. The minimum switching frequency is given by the Rt resistor value. This frequency is reached if there is no optocoupler or current feedback action and soft start period has been already finished. The maximum switching frequency excursion is limited by the Rfmax selection. Note that the Fmax value is influenced by the optocoupler saturation voltage value. Resistor Rfstart together with capacitor CSS prepares the soft start period after PFC timer elapses. The Rt pin is grounded via an internal switch during the PFC delay period to assure that the soft start capacitor will be fully discharged via Rfstart resistor. Constant LED current is achieved using a feedback loop monitoring the primary current. The sensing voltage must be scaled by the turns ratio of the transformer. The Rt pin reference voltage is VrefRt = 3.5 V. The control regulator operates on the difference between the Rt pin reference voltage and the minimum voltage compliance of the Brown−Out Protection The Brown−Out circuitry (BO) offers a way to protect the application from low DC input voltages. Operation is blocked below a set threshold. Hysteresis is provided by the switched current source providing stable operation. The internal circuitry, depicted by Figure 23, offers a way to monitor the high−voltage (HV) rail. www.onsemi.com 10 NCL30059 Vbulk Rupper BO + − + − Rlower 20ms Filter to BO_OK and gates VrefBO SW To PFC Delay IBO High Level for 50 ms after VCC On Figure 23. The internal Brown−Out Configuration with an Offset Current Sink internal BO_OK signal is high (PFC timer runs or Mlower and Mupper pulse), the IBO sink is deactivated. As a result, it becomes possible to select the turn−on and turn−off levels via a few lines of algebra: A resistive divider made of Rupper and Rlower, brings a portion of the HV rail on Pin 3. Below the turn−on level, the 18.2 mA current sink (IBO) is on. Therefore, the turn−on level is higher than the level given by the division ratio brought by the resistive divider.

BO Input Functionality − Vbulk < Vbulk2, PFC Start Follows Latched−Off Protection The IBO current sink is turned ON for 50 ms after any controller restart to let the BO input voltage stabilize (there can be connected big capacitor to the BO input and the IBO is only 18.2 mA so it will take some time to discharge). Once the 50 ms one shoot pulse ends the BO comparator is supposed to either hold the IBO sink turned ON (if the bulk voltage level is not sufficient) or let it turned OFF (if the bulk voltage is higher than Vbulk1). See Figures 25 through 28 for better understanding on how the BO input works. VCC There are some situations where the converter shall be fully turned−off and stay latched. This can happen in presence of an overvoltage (the feedback loop is drifting) or when an overtemperature is detected. Due to the addition of a comparator on the BO Pin, a simple external circuit can lift up this pin above Vlatch (2 V typical) and permanently disable pulses. The VCC needs to be cycled down below 6.5 V typically to reset the controller.

Adding a Comparator on the BO Pin Offers a Way to Latch−Off the Controller On Figure 29, Q1 is biased off and does not affect the BO measurement as long as the NTC and the optocoupler are not activated. As soon as the secondary optocoupler senses an OVP condition, or the NTC reacts to a high ambient temperature, Q1 base is biased on and the BO Pin goes up, permanently latching off the controller. The High−Voltage Driver Figure 30 shows the internal architecture of the high−voltage section. The device incorporates an upper UVLO circuitry that makes sure enough Vgs is available for the upper side MOSFET. The VCC for floating driver section is provided by Cboot capacitor that is refilled by external bootstrap diode. www.onsemi.com 14 NCL30059 Vboot Pulse Trigger Level Shifter S Q R Q Cboot Mupper HB UV Detect DEAD TIME Vbulk Dboot from PFC Delay B VCC Vaux + B A A Delay Mlower GND from latch high if OK Figure 30. The Internal High−Voltage Section of the NCL30059 The A and B outputs are delivered by the internal logic, as depicted in block diagram. This logic is constructed in such a way that the Mlower driver starts to pulse firs after any driver restart. The bootstrap capacitor is thus charged during first pulse. A delay is inserted in the lower rail to ensure good matching between these propagating signals. As stated in the maximum rating section, the floating portion can go up to 600 Vdc and makes the IC perfectly suitable for offline applications featuring a 400 V PFC front−end stage. www.onsemi.com 15 MECHANICAL CASE OUTLINE PACKAGE DIMENSIONS SOIC−8 NB CASE 751−07 ISSUE AK 8 1 SCALE 1:1 −X− DATE 16 FEB 2011 NOTES: 1.
