♠ 4.5V kupita ku 18V INPUT, 2-A SYNCCHRONOS STEP POWN CONVERTER NDI FET YOPHUNZITSIDWA
TPS54229 ndi chosinthira pa nthawi ya D-CAP2™ mode synchronous buck converter. TheTPS54229 imathandizira opanga makina kuti amalize zowongolera zamabasi amagetsi okhala ndi acost yogwira mtima, otsika kwambiri, njira yotsika yoyimirira pano. Njira yayikulu yowongolera ya TPS54229 imagwiritsa ntchito njira yowongolera ya D-CAP2™ yomwe imapereka kuyankha kwakanthawi kopanda zida zamalipiro zakunja. TPS54229 ilinso ndi dera lozungulira lomwe limathandiza kuti chipangizochi chizitengera ma capacitor otsika otsika (ESR), monga POSCAP kapena SP-CAP, ndi Ultra-low ESR ceramic capacitors. Chipangizocho chimagwira ntchito kuchokera ku 4.5-V mpaka 18-V VIN. Mphamvu yotulutsa imatha kukonzedwa pakati pa 0.76 V ndi 7 V. Chipangizocho chimakhalanso ndi nthawi yoyambira yofewa yosinthika. TPS54229 ikupezeka mu phukusi la 8-pin DDA, ndipo idapangidwa kuti izigwira ntchito kuyambira -40 ° C mpaka 85 ° C.
