♠ TPS62902, 3-V ilaa 17-V, Waxtarka Sare iyo Bedelka IQ Buck Hoose ee 1.5-mm × 2-mm Xidhmada QFN
TPS62902 waa wax-qabad heersare ah, yar, oo dabacsan oo isku-dhafan oo hoos-u-dhaca DC-DC-ga oo ay fududahay in la isticmaalo. Inta jeer ee wareejinta la dooran karo ee 2.5 MHz ama 1.0 MHz waxay ogolaataa isticmaalka inductors yar waxayna bixisaa jawaab degdeg ah oo ku meel gaar ah. Qalabku waxa uu taageeraa saxnaanta VOUT sare ee ± 1% oo leh DCS-Control topology. Kala duwanaanshaha korantada ballaaran ee 3-V ilaa 17-V waxay taageertaa noocyo kala duwan oo wax-soo-gelin ah, sida 12-V tareenada saadka, hal unug ama unugyo badan oo Li-Ion ah, iyo 5-V ama 3.3-V tareenada.
TPS62902 waxay si otomaatig ah u geli kartaa habka kaydinta tamarta (haddii auto PFM/PWM la doorto) marka la eego culeysyada fudud si loo ilaaliyo waxtarka sare. Intaa waxaa dheer, si loo bixiyo waxtarka sare ee culeyska aadka u yar, qalabku wuxuu leeyahay quescent yar oo hadda socda oo ah 4 µA. AEE, haddii la kartiyeeyo, waxay bixisaa hufnaan sare oo dhan VIN, VOUT, iyo load current. Qalabku waxa ku jira gelinta S-CONF/MODE si loo dejiyo qaybiyaha gudaha/dibadeedka, inta jeer ee beddelka, soo saarista korantada, iyo habka badbaadinta tooska ah ama hawlgalka PWM ee qasabka ah.
Qalabka waxaa lagu heli karaa xirmo yar oo 9-pin VQFN ah oo cabbirkeedu yahay 1.50 mm × 2.00 mm oo leh 0.5-mm garoon.
