I-MP8774H Synchronous Step-Down Converter

I-MPS 'MP8774H inokusebenza okulawula okufika ngesikhathi (COT) futhi inikeza impendulo esheshayo yesikhashana, ukwakheka kwe-loop elula, kanye nomthethonqubo wokukhishwa okuqinile

I-MPS 'MP8774H iyi-integrated integrated, high-frequency, synchronous, rectified, step-down, switch-mode converter ngamandla wangaphakathi we-MOSFET. Le divayisi ifinyelela i-12 A yokukhipha okuqhubekayo kwamanje ngomthwalo omuhle kakhulu nomthethonqubo womugqa kububanzi bokufaka obubanzi kusuka ku-3 V kuye ku-18 V. I-MP8774H isebenzisa ukusebenza kwemodi yokuvumelanisa ukuze isebenze kahle ngaphezu kwebanga lomthwalo okhishwayo wamanje. Izici zokuvikelwa ezigcwele zifaka ukuvikelwa kwesikhashana (i-SCP), ukuvikela ngokweqile (i-OCP), ukuvikelwa kwe-undervoltage (UVP), kanye nokuvala okushisayo. Ukusebenza kokulawulwa kwe-COT kunikeza impendulo yesikhashana esheshayo, ukwakheka kwe-loop okulula, kanye nomthethonqubo oqinile wokukhipha. I-MP8774H iyatholakala kuphakeji le-QFN-16 (3 mm x 3 mm).

Izici
  • Okukhiphayo okulungiswa kusuka ku-0.6 V

  • Ukuqalisa okwenziwe ngaphambilini
  • Imvamisa yokushintsha engu-1.4 MHz
  • Isikhathi sokuqala sokuthambisa esihlelwe ngaphandle
  • Nika amandla (EN) namandla okuhle (i-PG) ngokulandelana kwamandla
  • Ukuvikelwa ngokweqile nemodi ye-hiccup
  • Ukucisha ukushisa
  • Kutholakala kuphakeji le-QFN-16 (3 mm x 3 mm)
Izicelo
  • Amakhamera ezokuphepha
  • Ama-routers we-AP, amadivayisi we-XDSL
  • Amabhokisi we-digital set-top
  • Ithelevishini yephaneli elicabalele kanye nabaqaphi
  • Inhloso ejwayelekile
