♠ TPS62902, 3-V rau 17-V, Ua haujlwm siab thiab qis IQ Buck Converter hauv 1.5-mm × 2-mm QFN Pob
TPS62902 yog qhov ua tau zoo, me me, thiab hloov pauv hloov pauv hloov pauv DC-DC uas yooj yim siv. Ib qho kev xaiv hloov pauv zaus ntawm 2.5 MHz lossis 1.0 MHz tso cai siv cov inductors me me thiab muab cov lus teb ceev ceev. Cov cuab yeej txhawb siab VOUT qhov tseeb ntawm ± 1% nrog DCS-Control topology. Qhov dav input voltage ntau ntawm 3-V txog 17-V txhawb nqa ntau yam ntawm nominal inputs, xws li 12-V mov rails, ib leeg-cell lossis ntau-cell Li-Ion, thiab 5-V lossis 3.3-V rails.
TPS62902 tuaj yeem nkag mus rau lub zog txuag hom (yog tias nws pib PFM / PWM raug xaiv) ntawm lub teeb loads kom muaj kev ua haujlwm siab. Tsis tas li ntawd, txhawm rau muab kev ua haujlwm siab ntawm cov khoom me me, cov cuab yeej muaj qhov qis qis qis tam sim no ntawm 4 µA. AEE, yog tias qhib, muab kev ua haujlwm siab thoob plaws VIN, VOUT, thiab thauj khoom tam sim no. Cov cuab yeej suav nrog S-CONF/MODE cov tswv yim los teeb tsa lub sab hauv / sab nraud divider, hloov zaus, tso zis hluav taws xob, thiab tsis siv neeg lub zog txuag hom lossis yuam PWM ua haujlwm.
Cov cuab yeej muaj nyob rau hauv me me 9-pin VQFN pob ntsuas 1.50 hli × 2.00 hli nrog 0.5-mm suab.
• Kev ua haujlwm siab rau lub voj voog dav dav thiab kev thauj khoom ntau
