♠ 2 A, 1.5 MHz PWM step-down switching regulator nrog synchronous rectification
Lub ST1S09 yog ib kauj ruam-down DC-DC converter optimized rau powering low output voltage daim ntaub ntawv.Nws muab cov khoom siv tam sim no ntau tshaj 2 A dhau qhov kev tawm tswv yim voltage ntawm 2.7 V txog 6 V.
Lub siab PWM hloov zaus (1.5 MHz) tso cai rau siv cov khoom me me saum npoo-mount.
Ntxiv mus, txij li qhov xav tau synchronous rectifier yog kev koom ua ke, tus naj npawb ntawm cov khoom sab nraud raug txo kom tsawg: lub resistor divider, inductor thiab ob lub capacitor.CovLub Hwj Chim Zoo ua haujlwm tsis tu ncua saib xyuas cov zis hluav taws xob.Ib qho qhib qhov hluav taws xob zoo chij yog tso tawm thaum qhov tso zis hluav taws xob nyob hauv kev tswj hwm.Tsis tas li ntawd, qhov tso zis tsawg ripple yoglav los ntawm hom tam sim no PWM topology thiab los ntawm kev siv qis ESR SMD ceramic capacitors.Cov cuab yeej muaj kev tiv thaiv thermally thiab cov zis tam sim no txwv kom tsis txhob muaj kev puas tsuaj vimmus rau tej yam luv luv Circuit Court.ST1S09 muaj nyob rau hauv DFN6 (3 x 3 mm) pob.
