LCD面板用PWM信號(hào)生成器

BD9478F是LCD面板用PWM信號(hào)生成器。此IC通過(guò)對(duì)IC內(nèi)部產(chǎn)生的三角波與外部DC信號(hào)進(jìn)行比較，生成PWM信號(hào)。此PWM信號(hào)提供給LED驅(qū)動(dòng)器，對(duì)LED調(diào)光進(jìn)行控制。PWM脈沖頻率與輸入到SYNC端子的外部信號(hào)頻率同步。當(dāng)此頻率超過(guò)規(guī)定范圍時(shí)，則在設(shè)定頻率內(nèi)動(dòng)作以進(jìn)行保護(hù)，并常時(shí)向LED驅(qū)動(dòng)器提供穩(wěn)定的PWM脈沖。 ? The signal that the frequency synchronizes with the VSYNC signal is output to PWMOUT. \n? The PWM pulse is generated with the DC signal of a triangular wave and PDIM generated with the LCT capacitor. \n? When the VSYNC frequency exceeds the stipulated range, it fixes by a set frequency.
