TPS54615-EP 增强型产品 3V 至 6V 输入、6A 输出的同步降压 Pwm 转换开关，具有集成 Fet

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 TPS54611-6 devices are available in a thermally enhanced 28-pin TSSOP (PWP) PowerPAD™ package, which eliminates bulky heatsinks
