TPS5430DDAR DC-DC BUCK SWITCHING VOLTAGE REGULATORS SOP8

The TPS5430DDAR 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 are 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 5.5 V; an internally set slow-start circuit to limit inrush currents, and a voltage feedforward circuit to improve the transient response. Using the ENA pin, the shutdown supply current is reduced to 18 μA typically. Other features include an active-high enable, overcurrent limiting, over-voltage protection, and thermal shutdown. To reduce design complexity and external component count, the TPS5430 feedback loop is internally compensated. The TPS5431 is intended to operate from the power rails up to 23 V. The TPS5430 regulates a wide variety of power sources including a 24 V bus.
