UBA2016A/15/15A NXP Semiconductors 600 V fluorescent lamp driver 7.2.2 Protection The PFC incorporates the following protection mechanisms: • When voltage on pin FBPFC drops below open/short protection threshold voltage Vth(osp)(FBPFC), the gate is turned off and the start of a new cycle is inhibited. A small internal filter prevents this protection reacting to a negative spike.
UBA2016A/15/15A NXP Semiconductors 600 V fluorescent lamp driver 7.3.1 VDD supply The UBA2016A/15/15A is intended to be supplied by a start-up bleeder resistor connected between the bus voltage VBUS and VDD and a dV/dt supply from the half-bridge point at pin SHHB. The IC starts up when the voltage at pin VDD rises above start-up voltage Vstartup(VDD) and locks out (stops oscillating) when the voltage at pin VDD drops below stop voltage Vstop(VDD).

UBA2016A/15/15A NXP Semiconductors 600 V fluorescent lamp driver 7.4.1 Reset When voltage on pin VDD is below the reset voltage Vrst(VDD), both gates of the half-bridge driver are LOW. All internal latches are reset. When voltage on pin VDD rises above Vrst(VDD), the IC will enter STANDBY state. 7.4.2 Standby In STANDBY state the low-side gate driver is on (GLHB is HIGH).The floating supply capacitor CFSHB is then charged. When the VDD voltage rises above Vstartup(VDD), the Preheat state is entered. 7.

UBA2016A/15/15A NXP Semiconductors 600 V fluorescent lamp driver The preheat frequency for UBA2015 and UBA2015A can also be regulated via pin PH/EN. UBA2015 and UBA2015A support current controlled preheat and fixed frequency preheat. During preheat the output voltage of pin PH/EN is Vph(PH/EN).
UBA2016A/15/15A NXP Semiconductors 600 V fluorescent lamp driver 7.4.7.1 Lamp current control and dimming The AC lamp current is sensed by an external resistor connected to pin IFB. The resulting AC voltage on pin IFB is internally Double-Side Rectified (DSR), and compared to a reference level by an OTA. This reference level is determined by the internal reference regulation level Vreg(ref) and the voltage on the DIM input (UBA2015A and UBA2016A only), as shown in Figure 12 “Lamp current control”.

Lamp current control The output of the OTA is connected to pin CIFB.
UBA2016A/15/15A NXP Semiconductors 600 V fluorescent lamp driver However, the switching frequency can never go below fsw(low) (unless for UBA2016A when the boost function is active, see Section 7.4.7.3). If the regulation level is not reached at fsw(low) the IC will stay at fsw(low) (point E in Figure 10 and Figure 11). 7.4.7.2 Operation without lamp current control To operate the lamp without current control the lamp current sense pin IFB must be connected to ground.
UBA2016A/15/15A NXP Semiconductors 600 V fluorescent lamp driver The amount of boost depends on the current into the BOOST pin and the lamp current control. If the application does not use lamp current control, the switching frequency will go down to the lowest possible boost switching frequency fsw(bst)(low) (point G in Figure 11 “Resonance curve application with UBA2016A”) that is determined by Equation 1 or Equation 2, depending on the value of IBOOST.
UBA2016A/15/15A NXP Semiconductors 600 V fluorescent lamp driver A programmable end-of-life window is achieved by the internal bias current sink Ibias(EOL). The effective relative size of the EOL window will decrease in line with the increasing series resistance connected to pin EOL. The end-of-life lamp rectifying detection is only active during the Burn state. 7.6.2 End-of-life overvoltage detection This protection is intended to protect against symmetrical lamp aging.
UBA2016A/15/15A NXP Semiconductors 600 V fluorescent lamp driver During ignition a situation may occur where the amplitude of the load current is high and the half-bridge is at the boundary of capacitive mode switching; see Figure 14 “Switching”. The load current crosses zero during the non-overlap time. If the amplitude of the load current is large enough, the UBA2015 and UBA2015A might not detect capacitive mode because VSHHB did rise before going down again.

UBA2016A/15/15A NXP Semiconductors 600 V fluorescent lamp driver 7.6.6 Coil saturation protection When the peak voltage on pin SLHB exceeds saturation threshold voltage Vth(sat)SLHB, an additional current Iadd(CF) is sourced to pin CF to shorten the running oscillator cycle. In Ignition state the fault timer is started and a discharge current Idch(CIFB) is drawn from pin CIFB during the next cycle to increase the switching frequency.
UBA2016A/15/15A NXP Semiconductors 600 V fluorescent lamp driver timer is no longer detected for a period longer than the fault release delay time td(rel)fault, the fault timer will be reset and at any new occurance of the fault, the timer will start from zero. Faults which activate the fault timer are shown as SlowFault in Figure 9 “State diagram”. The fault timer uses the same pin (CPT) to set the time with an external capacitor Cext(CPT) as the preheat timer.

The tolerance of this resistor adds to any current related tolerances of the IC, including fsw(low). No other components can be connected to pin IREF. Tolerance and temperature dependency of the capacitor connected between pin CF and GND will add to the tolerance on fsw(low).
