9. Functional Description
When power is turned on, the IRS2530D first starts in Under Voltage Lockout (UVLO)
mode. The UVLO mode is designed to maintain an ultra-low (<250 A) supply current,
and to guarantee that the IC is fully functional before the high- and low-side output (HO
and LO) gate drivers are activated. During UVLO, HO is ‘low’, and VCO is pulled down
to COM for resetting the starting frequency to the maximum. LO is open circuit, and is
used as a shutdown/reset input function for automatically restarting the IC when a lamp
has been removed and re-inserted.
Once VCC reaches the startup threshold (VCCUV+) and the LO pin is below VLOSD-
(lamp is inserted), the half-bridge FETs start to oscillate and the IC enters
Preheat/Ignition Mode. At startup, VCO is 0V and the frequency starts at f MAX . The
frequency ramps down towards the resonant frequency of the high-Q ballast output
stage, causing the lamp voltage to increase. During this time, the filaments of the lamp
are pre-heated to their emission temperature to minimize the necessary ignition voltage
and to increase lamp life. The voltage on pin VCO continues to increase and the
frequency keeps decreasing until the lamp ignites. If the lamp ignites successfully, the
IRS2530D enters the DIM mode. The resonant output stage transitions to a series-L,
parallel RC circuit with the Q-value and operating point determined by the user dim level
