The constant output current is especially useful for light emitting diode (LED) applications. The switching regulator function is implemented by a pulse width modulated (PWM) current mode controller. The PWM current mode controller uses the peak current through the external power switch and error in the output current to determine the appropriate pulse width duty cycle (on time) for constant output current. The current mode controller provides a PWM signal to an internal gate driver which then outputs to an external nchannel enhancement mode metal oxide field effect transistor (MOSFET) power switch. The current mode controller also has built-in slope compensation to prevent sub-harmonic oscillations which is a characteristic of current mode controllers operating at high duty cycles (>50% duty). An additional built-in feature is an integrated soft start that limits the current through the inductor and external power switch during initialization. The soft start function gradually increases the inductor and switch current over tSS (Parameter 5.2.9) to minimize potential overvoltage at the output.

The switching frequency can be selected from 100 kHz to 500 kHz with an external resistor to GND. To set the switching frequency with an external resistor the following formula can be applied. (6.1) ( R FREQ = (141 ⋅ 10 − 12 1 − 3 . 5 ⋅ 10 ⎡ s ⎤ ⎛ ⎡1 ⎤ ⎞ ⋅ ) f ⎜ ⎟ FREQ ⎢⎣ Ω ⎥⎦ ⎢⎣ s ⎥⎦ ⎝ ⎠ 3 [Ω ])[Ω ] In addition, the oscillator is capable of changing from the frequency set by the external resistor to a synchronized frequency from an external clock source. If an external clock source is provided on the pin FREQ/SYNC, then the internal oscillator synchronizes to this external clock frequency and the boost regulator switches at the synchronized frequency. The synchronization frequency capture range is 250 kHz to 500 kHz.

A valid logic LOW signal on enable pin EN/PWMI powers OFF the device and current consumption is less than Iq_OFF (Parameter 7.2.8). A valid logic HIGH enable signal on enable pin EN/PWMI powers on the device. The enable function features an integrated pull down resistor which ensures that the IC is shut down and the power switch is OFF in case the enable pin EN is left open. In addition to the enable function described above, the EN/PWMI pin detects a pulse width modulated (PWM) input signal that is fed through to the internal gate driver. The EN/PWMI enables and disables the gate driver for the main switch during PWM operation. PWM dimming an LED is a commonly practiced dimming method and can prevent color shift in an LED light source. The enable and PWM input function share the same pin. Therefore a valid logic LOW signal at the EN/PWMI pin needs to differentiate between an enable power OFF or an PWM dimming LOW signal. The device differentiates between enable OFF and PWM dimming signal by requiring the enable OFF at the EN/PWMI pin to stay LOW for the Enable Turn OFF Delay Time (tEN,OFF,DEL Parameter 7.2.6).

Data Sheet 19 Revision 1.0 2015-03-12 Infineon® LITIX™ Power TLD5097EL Linear Regulator 8 Linear Regulator Description The internal linear voltage regulator supplies the internal gate drivers with a typical voltage of 5 V and current up to ILIM,min (parameter P_8.1.2). An external output capacitor with ESR lower than RIVCC,ESR (parameter P_8.1.5) is required on pin IVCC for stability and buffering transient load currents. During normal operation the external MOSFET switches will draw transient currents from the linear regulator and its output capacitor. Proper sizing of the output capacitor must be considered to supply sufficient peak current to the gate of the external MOSFET switches. Integrated Undervoltage Protection for the External Switching MOSFET An integrated undervoltage reset threshold circuit monitors the linear regulator output voltage (VIVCC) and resets the device in case the output voltage falls below the IVCC undervoltage reset switch OFF threshold (VIVCC,RTH,d). The undervoltage reset threshold for the IVCC pin helps to protect the external switches from excessive power dissipation by ensuring the gate drive voltage is sufficient to enhance the gate of an external logic level n-channel MOSFET.

Data Sheet 21 Revision 1.0 2015-03-12 Infineon® LITIX™ Power TLD5097EL Protection and Diagnostic Functions 9 Protection and Diagnostic Functions 9.1 Description The TLD5097EL has integrated circuits to diagnose and protect against output overvoltage, open load, open feedback and overtemperature faults. In case of a fault condition, the SWO signal stops operation. The ST signal will change to an active logic LOW signal to communicate that a fault has occurred (detailed overview in Figure 9-1and Figure 9-2 below). Figure 9-3 illustrates the various open load and open feedback conditions. In case of an overtemperature condition the integrated thermal shutdown function turns off the gate driver and internal linear voltage regulator. The typical junction shutdown temperature is 175°C (Tj,SD Parameter 9.2.3). After cooling down the IC will automatically restart. Thermal shutdown is an integrated protection function designed to prevent IC destruction and is not intended for continuous use in normal operation (Figure 9-5). To calculate the proper overvoltage protection resistor values an example is given in Figure 9-6.

Data Sheet 26 Revision 1.0 2015-03-12 Infineon® LITIX™ Power TLD5097EL Analog Dimming 10 Analog Dimming This pin is influencing the Feedback Voltage Error Amplifier by generating an internal current accordingly to an external reference voltage (VSET). If the analog dimming feature is not needed this pin must be connected to IVCC or external > 1.6V supply. Different application scenarios are described in Figure 10-3. This pin can also go outside of the ECU for instance if a thermistor is connected on a separated LED Module and the Analog Dimming Input is used to thermally protect the LEDs. For reverse battery protection of this pin an external series resistor should be placed to limit the current. 10.1 Purpose of Analog Dimming 1. It is difficult for LED manufacturers to deliver LEDs which have the same Brightness, Colorpoint and Forward Voltage Class. Due to this relatively wide spread of the crucial LED parameters automotive customers order LEDs from one or maximum two different colorpoint classes. The LED manufacturer must preselect the LEDs to deliver the requested colorpoint class. Those preselected LEDs are matched in terms of the colorpoint but a variation of the brightness remains. To correct the brightness deviation an analog dimming feature is needed. The mean LED current can be adjusted by applying an external voltage VSET at the SET pin. 2. If the DC/DC application is separated from the LED loads the ECU manufacturers aim is to develop one hardware which should be able to handle different load current conditions (e.g. 80mA to 400mA) to cover different applications. To achieve this average LED current adjustment the analog dimming is a crucial feature. 10.2 Description Application Example Desired LED current = 400mA. For the calculation of the correct Feedback Resistor RFB the following equation can be used: This formula is valid if the analog dimming feature is disabled and VSET > 1.6V. (10.1) I LED = VREF V 0.3V → RFB = REF → RFB = = 750mΩ RFB I LED 400mA A decrease of the average LED current can be achieved by controlling the voltage at the SET pin (VSET) between 0V and 1.6V. The mathematical relation is given in the formula below: (10.2) I LED = VSET − 0.1V 5 ⋅ RFB If VSET is 100mV the LED current is only determined by the internal offset voltages of the comparators. For this example ILED = 0A if VSET < 100mV. Refer to the concept drawing in Figure 10-2.

A µC integrated digital analog converter (DAC) output or a stand alone DAC can be used to supply the SET pin of the TLD5097EL. The integrated voltage Regulator (VIVCC) can be used to supply the µC or external components if the current consumption does not exceed 20mA. 2. The analog dimming feature is directly connected to the input voltage of the system. In this configuration the LED current is reduced if the input voltage VIN is decreasing. The DC/DC boost converter is changing (increasing) the switching duty cycle if VIN drops to a lower potential. This is causing an increase of the input current consumption. If applications require a decrease of the LED current in respect to VIN variations this setup can be choosen. 3. The usage of an external resistor divider connected between IVCC (integrated 5V regulator output and gate buffer pin) SET and GND can be choosen for systems without µC on board. The concept allows to control the LED current via placing cheap low power resistors. Furthermore a temperature sensitive resistor (Thermistor) to protect the LED loads from thermal destruction can be connected additionally. 4. If the analog dimming feature is not needed the SET pin must be connected directly to >1.6V potential (e.g. IVCC potential) 5. Instead of an DAC the µC can provide a PWM signal and an external R-C filter is producing a constant voltage for the analog dimming. The voltage level is depending on the PWM frequency (fPWM) and duty cycle (DC) which can be controlled by the µc software after reading the coding resistor placed at the LED module.
