♠ LM5176 55-V Wide VIN Tukutahi 4-whakawhiti Buck-boost Kaiwhakahaere
Ko te LM5176 he kaiwhakahaere DC/DC tukutahi e wha-whakawhiti ka taea te whakahaere i te ngaohiko whakaputa i runga, i raro ranei i te ngaohiko whakauru. Ko te LM5176 e mahi ana i runga i te awhe ngaohiko whakauru whanui o 4.2 V ki te 55 V (60-V tino teitei) hei tautoko i nga momo tono.
Ka whakamahia e te LM5176 te mana whakahaere o naianei i roto i te peera me te whakanui i nga momo mahi mo te utaina pai ake me te ture raina. Ko te auau whakawhiti ka whakaritea e te parenga o waho ka taea te tukutahi ki te tohu karaka o waho.
Kei roto hoki i te taputapu he mahi tiimata ngawari ka taea te whakamaarama me te tuku i nga ahuatanga whakamarumaru tae atu ki te hurihanga ma-hurihuri te aukati o naianei, te maukati i raro i te ngaohiko whakauru (UVLO), te whakamarumaru i te ngaohiko putanga (OVP), me te whakaweto waiariki. I tua atu, kei te LM5176 te whakaurunga toharite, te whakawhāititanga o te putanga o naianei, te hihinga horahanga hei whakaiti i te tihi o te EMI, me te tiaki aratau hiccup i roto i nga ahuatanga taumaha tonu.
