Atụmatụ maka LP8867-Q1
- AEC-Q100 ruru eru maka ngwa ụgbọ ala:
- Igwe okpomọkụ ọkwa 1:
- -40C ruo +125C, TA
- Nchekwa arụ ọrụ nwere ike
- Akwụkwọ dị iji nyere aka chepụta sistemụ nchekwa ọrụ
- 3-, 4-Channel 120-mA dị ugbu a sink
- Oke ngbanwe dị elu nke 10 000:1 na 100 Hz
- Dakọtara ugbu a 1% (nke a na-ahụkarị)
- eriri LED ugbu a ruo 120mA kwa ọwa
- Enwere ike ijikọ nsonaazụ na mpụga maka oke ugbu a kwa eriri
- Mgbakwunye agbakọta na ihe ntụgharị SEPIC maka ike eriri LED
- Ntinye voltaji na-arụ ọrụ nso 4.5 V ruo 40 V
- Mpụta voltaji ruo 45 V
- Ejikọtara 3.3-A Switch FET
- Ịgbanwe ugboro 300 kHz ka 2.2 MHz
- Ịgbanwe ntinye mmekọrịta
- Gbasaa ụdịdị dị iche iche maka EMI dị ala
- Nchọpụta mmejọ na nchebe
- Mbipụta mmejọ

Nkọwa maka LP8867-Q1
LP8867-Q1, LP8869-Q1 bụ ụgbọ ala jikọtara nke ukwuu, dị ala-EMI, dị mfe iji ọkụ ọkụ nwere onye ntụgharị DC-DC.Ihe ntụgharị DC-DC na-akwado ma nkwalite yana ọrụ SEPIC mode.Ngwa ahụ nwere mmiri mmiri anọ ma ọ bụ atọ dị elu nke nwere ike jikọta maka ike dị elu ugbu a.
Ihe ntụgharị DC-DC nwere njikwa voltaji na-agbanwe agbanwe dabere na voltaji na-ebugharị LED.Njirimara a na-ebelata oriri ike site n'ịgbanwe voltaji na ọkwa kachasị ala na ọnọdụ niile.Maka mbelata EMI DC-DC na-akwado ịgbasa ụdịdị dị iche iche maka ịgbanye ugboro ole yana mmekọrịta mpụga nwere pin raara onwe ya nye.Ugboro mgbanwe n'obosara na-enye ohere LP886x-Q1 iji zere ọgbaghara maka bandwit nwere mmetụta.
Oke ntinye voltaji maka LP886x-Q1 sitere na 4.5 V ruo 40 V iji kwado mmalite nkwụsị ụgbọ ala na ọnọdụ mkpofu ibu.LP886x-Q1 na-ejikọta ọtụtụ njirimara nchọpụta mmejọ.
