TPS54610

具有可调节输出电压的低输入电压 6A 同步降压转换器

As a member of the SWIFT™ family of dc/dc regulators, the low-input voltage high-output current synchronous buck 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; an internally or externally set slow-start circuit to limit inrush currents; and a power good output useful for processor/logic reset, fault signaling, and supply sequencing.

The TPS54610 is available in a thermally enhanced 28-pin HTSSOP PWP PowerPAD™ package, which eliminates bulky heatsinks. 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.
