TPS54612 具有 1.2V 输出的低输入电压 6A 同步降压转换器
TPS54612 描述
The SWIFT™ family of dc/dc regulators, the TPS54611, TPS54612, TPS54613, TPS54614, TPS54615 and TPS54616 low-input voltage high-output current synchronous-buck PWM converters integrate all required active components. Included on the substrate are true, high-performance, voltage error amplifiers that provide high performance under transient conditions; an under-voltage-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.
The TPS54612–6 devices are available in a thermally enhanced 28-pin TSSOP (PWP) PowerPAD™ package, which eliminates bulky heatsinks.
