TPS5410 2A 宽输入范围步降 Swift(TM) 转换器
TPS5410 描述
As a member of the SWIFTTM family of DC/DC regulators, the TPS5410 is a high-output-current PWM converter that integrates a low resistance high side N-channel MOSFET. Included on the substrate with the listed features is a high performance voltage error amplifier that provides tight voltage regulation accuracy under transient conditions; an undervoltage-lockout circuit to prevent start-up until the input voltage reaches 5.5 V; an internally set slow-start circuit to limit inrush currents; and a voltage feed-forward circuit to improve the transient response. Using the ENA pin, shutdown supply current is reduced to 18 uA typically. Other features include an active high enable, overcurrent limiting, overvoltage protection and thermal shutdown.
