♠ LM2775 Hloov Capacitor 5-V Boost Converter

LM2775 yog ib qho kev hloov pauv-capacitor doubler uas ua rau lub suab nrov qis.Lub LM2775 tuaj yeem muab tau txog 200 mA ntawm cov zis tam sim no dhau ntawm 3.1-V txog 5.5-V input ntau yam, nrog rau txog li 125 mA ntawm cov zis tam sim no thaum lub input voltage tsawg li 2.7 V. Ntawm cov zis tawm tam sim no, LM2775 tuaj yeem txo nws qhov quiescent tam sim no los ntawm kev khiav hauj lwm hauv ib hom mem tes zaus (PFM) hom.PFM hom tuaj yeem qhib lossis tsis ua haujlwm los ntawm kev tsav lub PFM tus pin kom siab lossis qis.Tsis tas li ntawd, thaum LM2775 raug kaw, tus neeg siv tuaj yeem xaiv kom muaj qhov tso zis hluav taws xob rub mus rau GND lossis sab laug hauv lub xeev siab impedance los ntawm kev teeb tsa OUTDIS tus pin siab lossis qis.

Lub LM2775 tau muab tso rau hauv TI's 8-pin WSON, ib pob nrog cov khoom siv thermal zoo uas ua rau ib feem los ntawm overheating nyob rau hauv yuav luag txhua qhov ntsuas kev ua haujlwm.
