(the above figure uses in1 to control current) (1) when starting, the output voltage " v o " is determined by the feedback to in2 via r1 and r2 and the following equation: v o = v ref (r1 + r2) / r2 (v ref = 1.25 v typ) (area of the timing chart 1) (2) next, this output voltage " v o " is used to discharge the fl tube by the inverter and causes the tube current to flow. the tube current is filtered and smoothed by r fl , d2, and c fl so that the dc voltage (v cfl ) corresponding to the tube current is generated at c fl . the voltage of v cfl is divided by r3, v r1 , and r4, and feedback to in1, it can control tube current. (area of the timing chart 2) (3) here, c delay is inserted between r3 and v r1 + r4 in order to regulate the timing to switch from the voltage control to the current control. (area of the timing chart 3) (4) when in the current control state, it is possible to adjust brightness by changing the amount of feedback of the tube current using v r1 . (area of the timing chart 4) (5) if the feedback used for controlling current is lost due to irregularities in the fl tube. etc. the control returns to the voltage contro l mode. (area of the timing chart 5)

(goes up slowly from 0 v) thus, approximately 35 a current will flow when sw1: on and sw2: off. the potential, namely the potential of the fb terminal is in the amplitude of the triangular wave, sw1 will be off and sw2 will be on and approximately 45 a will flow into the dtc terminal. this discharge current will cause the dtc terminal to drop from 1.15 v. at this time, if the potential of the fb terminal goes to the control potential before the potential at the dtc terminal goes lower than 0.45 v which is the lower limit value of the triangular wave and if the potential of the fb terminal is lower than the potential of the dtc terminal, then the system is activated. when the output is shorted, the system is either activat ed or latched depending on whether the time for the high potential of the fb terminal reaches the potential of the contro l state is long or short. (for detail, see [ii] and [iv] of the mode) there are two ways to go back to operation after the latch to shut off output. either method can restart with soft start. 1. turning on the v cc . 2. make the fb terminal to go to the low potential of 1.25 v or less. then, it is cancelled.
m62211p/fp rej03d0842-0201 rev.2.01 nov 14, 2007 page 9 of 11 [mode explained] [i] mode?............. activation this is used when the fb terminal goes down to the control state potential when the dtc terminal is in up slope. in order for the activation to occur when the dtc terminal is in down slope, the fb terminal potential must go below the dtc terminal before the dtc terminal goes to 0.45 v. [ii] mode?........... output short activation the system is activated if the fb terminal potential goes below the dtc terminal potential before the dtc terminal goes to 0.45 v. if there is not enough time, the output is turned off. (latched) [iii] mode?.......... on/off control activation this mode turns off the output by forcing the dtc terminal to go down. (the system) returns as in the case of the activation. [iv] mode?.......... output short (latch) the output is turned off when the fb terminal potential did not go down to the control state before the dtc terminal went down to 0.45 v.
