♠ TPS65251 4.5-V kusvika 18-V Input, Yepamusoro-Irizvino, Synchronous Nhanho-Pasi Matatu Buck Switcher Ine Yakabatanidzwa FET
Iyo TPS65251 inoratidzira matatu akaenzana akafara ekuisa huwandu hwakanyanya kushanda zvakanaka buck converters. Iwo anoshandura akagadzirirwa kurerutsa mashandisirwo ayo achipa mugadziri sarudzo yekukwirisa mashandisiro azvo zvinoenderana nechinangwa chekushandisa.
Iwo anoshandura anogona kushanda mu5-, 9-, 12- kana 15-V masisitimu uye ane akabatanidza magetsi transistors. Iyo inobuda voltage inogona kusetwa kunze uchishandisa resistor divider kune chero kukosha pakati pe 0.8 V uye padhuze neiyo yekuisa. Yese inoshandura maficha anogonesa pini inobvumira kunonoka kutanga-up kwezvinangwa zvekutevedzana, nyoro-yekutanga pini inobvumira inogadzirika yakapfava-yekutanga nguva nekusarudza yakapfava-yekutanga capacitor, uye yazvino muganhu (RLIMx) pini inogonesa mugadziri kugadzirisa ikozvino muganhu nekusarudza yekunze resistor uye optimize sarudzo yeinductor. Ikozvino modhi yekudzora inobvumira iri nyore RC muripo.
Iyo yekuchinjisa frequency yevashanduri inogona kuseta neyekunze resistor yakabatana neROSC pini kana inogona kuwiriraniswa kune yekunze wachi yakabatana neSYNC pini kana zvichidikanwa. Iwo ma switching regulators akagadzirirwa kushanda kubva pa300 kHz kusvika 2.2 MHz. 180 ° kunze kwechikamu chekushanda pakati peBuck 1 neBuck 2, 3 (Buck 2 uye 3 inomhanya muchikamu) inoderedza zvinodiwa zvesefa.
