TPS54672中文资料6A 有源总线终端/DDR 存储器 SWIFT™ 转换器数据手册TI规格书

描述 Description

As a member of the SWIFT™ family of dc/dc regulators, the TPS54672 active bus termination synchronous PWM converter integrates all required active components. Included on the substrate with the listed features are a true, high performance, voltage error amplifier that enables maximum performance and flexibility in choosing the output filter L and C components; an under-voltage-lockout circuit to prevent start-up until the input voltage reaches 3 V; a slow-start control to limit in-rush currents; and a status output to indicate valid operating conditions.

The TPS54672 is available in a thermally enhanced 28-pin TSSOP (PWP) PowerPAD™ package, which eliminates bulky heatsinks. TI provides evaluation modules and the SWIFT™ designer software tool to aid in quickly achieving high-performance power supply designs to meet aggressive equipment development cycles.
