... The ignition mode is defined as the state the when a high voltage is being established across the lamp necessary for igniting the lamp. The IR2166 enters ignition mode when the voltage on pin CPH exceeds 10V. Pin CPH is connected internally to the gate of a P-channel MOSFET (S4) (see Figure 4) that connects pin RPH with pin RT ...

... AC line input voltage, produces an AC line input current. The control method implemented in the IR2166 is for a boost- type converter (Figure 6) running in critical- conduction mode (CCM). This means that during each switching cycle of the PFC MOSFET, the circuit waits until the inductor current discharges to zero before turning the PFC MOSFET on again ...

... LPFC flows into CBUS. As MPFC is turned on and off at a high-frequency, the voltage on CBUS charges specified voltage. The feedback loop of the IR2166 regulates this voltage to a fixed value by continuously monitoring the DC voltage and adjusting the on-time of MPFC accordingly. For an increasing DC bus the on- time is decreased, and for a decreasing DC bus the on-time is increased ...

... CBUS RPFC MPFC ZX 7 7.6V Figure 9: IR2166 detailed PFC control circuit The off-time of MPFC is determined by the time it takes the LPFC current to discharge to zero. This zero current level is detected by a secondary winding on LPFC which is connected to the ZX pin. A positive-going edge exceeding the internal 2V threshold signals the beginning of the off-time ...

... IR2166 & (PbF) modulation circuit has been added to the PFC control. This circuit dynamically increases the on-time of MPFC as the line input voltage nears the zero-crossings (Figure 11). This causes the ...

... PFC and ballast sections are disabled (see State Diagram). The start-up supply resistor to VCC, together with the micro- power start-up current of the IR2166, determine the line input turn-on voltage. This should be set such that the ballast turns line voltage level above the under-voltage turn-off level ...

... VBUS pin does not become active until RUN mode). For these reasons, the ballast designer should perform these mains interrupt and ignition tests carefully to determine the robustness of their final design and to decide if this additional over-current protection circuit is necessary.

... IR2166 & (PbF) Ballast Design Equations Note: The results from the following design equations can differ slightly from experimental measurements due to IC tolerances, component tolerances, and oscillator over- and undershoot due to internal comparator response time.

... This threshold determines the over-current limit of the ballast, which can be exceeded when the frequency ramps down towards resonance during ignition and the lamp does not ignite. The maximum ignition current is given as IGN [Amps Peak] ( IGN www.irf.com [Ohms] (10) IR2166 & (PbF) 29 ...
