臺(tái)灣致新(GMT)*新推出5V/3A 同步整流升壓IC---G2118F11U SOP-8 *小包裝2500/盤,可提供樣品及技術(shù)支持!價(jià)格請(qǐng)來(lái)電咨詢我。
g2118是一個(gè)緊湊的,高效率,同步升壓轉(zhuǎn)換器的功率MOSFET嵌入式具有輸出關(guān)斷真關(guān)機(jī)功能,可調(diào)輸出電流限制為一個(gè)單一的折返—
電池鋰離子/聚合物電池。的g2118只使用100μ一(典型值)靜態(tài)電流和允許轉(zhuǎn)換僅當(dāng)需要時(shí),無(wú)負(fù)載和輕負(fù)載,當(dāng)負(fù)荷大于100mA,它使用固定頻率PWM技術(shù)在500kHz。它的特點(diǎn)快速瞬態(tài)響應(yīng)的電流模式控制內(nèi)部補(bǔ)償。g2118包括周期—按循環(huán)電流限制*大電感電流
過(guò)溫保護(hù)電路。g2118適用于ipad的電腦一樣,智能手機(jī)和便攜式手持設(shè)備。
