Product Details

Part no.	TPS54291PWPR
Packge/Case	TSSOP16
Manutacturer	TI
Description	转换器 1.5-A/2.5-A Dual, Fully-Synchronous Buck Converter With Integrated MOSFET
Datasheet	Check Datasheet

The TPS54290, TPS54291, and TPS54292 devices are dual-output, fully synchronous buck converters capable of supporting applications with a minimal number of external components. It operates from a 4.5-V to 18-V input supply voltage, and supports output voltages as low as 0.8 V and as high as 90% of the input voltage.

Both high-side and low-side MOSFETs are integrated to provide fully synchronous conversion with higher efficiency. Channel 1 can provide up to 1.5 A of continuous current. Meanwhile, Channel 2 supports up to 2.5 A.

Current mode control simplifies the compensation. The external compensation adds flexibility for the user to choose different type of output capacitors.

180° out-of-phase operation reduces the ripple current through the input capacitor, providing the benefit of reducing input capacitance, alleviating EMI and increasing capacitor life.

的tps54290，tps54291，和tps54292设备双输出，完全同步降压转换器，能够用最少的外部元件数目的配套应用。它从一个4.5-v至18-V输入电源电压，并支持输出电压低至0.8 V和输入电压的高90%。
高侧和低侧MOSFET的集成，以提供更高的效率完全同步转换。通道1可提供多达1.5个连续电流。同时，通道2支持最多2.5 A。
电流模式控制简化了补偿。外部补偿增加了用户选择不同类型的输出电容器的灵活性。
180°过相操作减少了通过输入电容器的纹波电流，提供了降低输入电容、减轻电磁干扰和提高电容器寿命的好处。

	Seller(Anderson) Reply: 根据百联集团此前发布的公告，阿里巴巴受让联华超市已发行股本的18%，成为第二大股东。值得注意的是，公告特别指出易果生鲜仍持有1.17%的股份，将继续发挥其在生鲜供应链和物流方面长期积累的优势，与联华超市形成战略互补和业务协同。2017-06-01 According to the Bailian Group previously released announcement, the Alibaba Lianhua Supermarket issued share capital of 18%, becoming the second largest shareholder. It is worth noting that the announcement noted that fresh fruit is easy to hold 1.17% of the shares, will continue to play its long-term accumulation in fresh supply chain and logistics advantages, the formation of strategic complementarity and collaborative business and Lianhua supermarket. 2017-06-01 これまでに発表された公告によって百聨グループ、アリババ譲り受け聯華超市発行済み株式の18％、第2位の株主。注意すべきことは、特に指摘し公告易果生鮮はまだ保持1.17%の株式は、プレイを続けて、生鮮サプライチェーンや物流面で長期に蓄積の利点は、聯華超市と形成戦略補完と業務の共同。2017-06-01
