4 V至6 V的输入, 8 -A输出同步降压有残疾塌陷SWITCHER易电源启动时 4-V TO 6-V INPUT, 8-A OUTPUT SYNCHRONOUS BUCK SWITCHER WITH DISABLED SINKING DURING START-UP
As a member of the SWIFT family of dc/dc regulators, family of dc/dc regulators,the TPS54873 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 4 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.
For reliable power up in output precharge applications, the TPS54873 is designed to only source current during startup.
The TPS54873 is available in a thermally enhanced 28-pin TSSOP 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.
