1.6兆赫, 3 V至6 V的输入, 3 -A同步降压型转换器SWIFT⑩禁用塌陷启动时 1.6 MHz, 3-V TO 6-V INPUT, 3-A SYNCHRONOUS STEP-DOWN SWIFT⑩ CONVERTER WITH DISABLED SINKING DURING START-UP
As a member of the SWIFT™ family of dc/dc regulators, the TPS54377 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 provides high performance under transient conditions; an undervoltage-lockout circuit to prevent start-up until the input voltage reaches 3 V; an internally and externally set slow-start circuit to limit in-rush 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 TPS54377 is designed to only source current during start-up.
The TPS54377 device is available in a thermally enhanced 24-pin QFN RHF PowerPAD package, which eliminates bulky heatsinks. provides evaluation modules and the SWIFT designer software tool to aid in achieving high-performance power supply designs to meet aggressive equipment development cycles.
