♠ LP8866S-Q1 Magalimoto Owonetsa LED-backlight Dalaivala yokhala ndi Makanema asanu ndi limodzi a 150-mA
LP8866S-Q1 ndi galimoto yoyendetsa bwino kwambiri ya LED yokhala ndi chowongolera chowongolera. Six highprecision current sinks imathandizira kusintha kwa gawo komwe kumasinthidwa zokha kutengera kuchuluka kwa ma tchanelo omwe akugwiritsidwa ntchito. Kuwala kwa LED kumatha kuwongoleredwa padziko lonse lapansi kudzera mu mawonekedwe a I²C kapena kulowetsa kwa PWM.
Chowongolera chowongolera chimakhala ndi zowongolera zotulutsa magetsi kutengera ma voltages akumutu akumira kwamakono a LED. Izi zimachepetsa kugwiritsa ntchito mphamvu posintha mphamvu yamagetsi kuti ikhale yotsika kwambiri m'mikhalidwe yonse. Ma frequency osinthika osiyanasiyana amalola LP8866S-Q1 kupewa kusokoneza band ya wailesi ya AM.
LP8866S-Q1 imathandizira dimming ya haibridi ya PWM ndi dimming ya analogi, yomwe imachepetsa EMI, imakulitsa moyo wa LED, ndikuwonjezera mphamvu yonse ya kuwala.
• AEC-Q100 yoyenerera kugwiritsa ntchito magalimoto:
- Kutentha kwa chipangizo kalasi 1:
-40°C mpaka +125°C, TA
- Chida cha HBM ESD classification level 2
- Chipangizo CDM ESD gulu mlingo C4B
• Mphamvu yamagetsi yolowera 3 V mpaka 48 V
• Masinki asanu ndi limodzi olondola kwambiri
- Kufikira 150-mA DC yapano pakuzama kulikonse komwe kulipo
- Zofananira 1% (zofanana)
- Dimming ratio 32 000: 1 pogwiritsa ntchito 152-Hz LED yotulutsa PWM pafupipafupi
- Kufikira ku 16-bit LED dimming resolution yokhala ndi I2C, kapena kulowetsa kwa PWM
- 8 Kusintha kwa zingwe za LED
• Auto-gawo shift shift PWM dimming
• 12-bit analogi dimming
• Kufikira 48-V VOUT boost kapena SEPIC DC/DC controller
- Kusintha pafupipafupi 100 kHz kupita ku 2.2 MHz
- Limbikitsani kufalikira kwa EMI yochepetsedwa
- Limbikitsani zolumikizira kuti mukhazikitse ma frequency osinthika kuchokera pawotchi yakunja
- Magetsi otulutsa amangotulutsidwa pokhapokha mphamvu ikayimitsidwa
• Kuzindikira zolakwika zambiri
• Nyali yakumbuyo ya:
- infotainment yamagalimoto
- Magulu a zida zamagalimoto
-Magalasi anzeru
- Mawonekedwe apamwamba (HUD)
