TPS5410D
TEXAS INSTRUMENTS TPS5410D 直流-直流开关降压逐步递减稳压器, 可调, 5.5V-36V输入, 1.22V-31V输出, 1A输出, SOIC-8
The is a 1A 500kHz Step-down 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 under-voltage-lockout circuit to prevent start-up until the input voltage reaches 5.5V, 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 18µA typically. Other features include an active high enable, over-current limiting, overvoltage protection and thermal shutdown. To reduce design complexity and external component count, the TPS5410 feedback loop is internally compensated.
