TPS54972PWP

9 -A输出， 3 V至4 -V具有集成FET输入跟踪/终止同步PWM SWITCHER 9-A OUTPUT, 3-V TO 4-V INPUT TRACKING/TERMINATION SYNCHRONOUS PWM SWITCHER WITH INTEGRATED FETS

As a member of the SWIFT™ family of dc/dc regulators, the TPS54972 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 under transient conditions 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 3.0 V; an internally set slow-start circuit to limit in-rush currents; and a status output to indicate valid operating conditions.

The TPS54972 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.
