The LT3467AIDDB# TRPBF belongs to the PMIC - Voltage Regulators - DC DC Switching Regulators category. Specifically, this high efficiency synchronous step-down switching regulator is designed for applications that require step down, low noise and high efficiency power conversion. It can provide regulated output voltages from 0.8V to 5.5V with an operating input voltage range of 4V to 28V, making it well suited for various DC/DC conversion applications.

The LT3467AIDDB# TRPBF is based on a synchronous buck topology, whereby the input voltage is transferred directly to the output voltage, across a synchronous rectifying switching transistor. This switching transistor, which is driven by a control circuit, switches on and off, at a variable pulse rate, controlling the load current and output voltage. As the voltage input increases, the switching pulse rate increases, and vice versa, until the power output is regulated.

This switching regulator can reach high peak efficiencies, up to 95%, making it well suited for power-sensitive applications. The operating temperature range is -40°C to +125°C. This product also features a linear post-regulation to reduce output voltage noise and improve ripple rejection. Furthermore, a phase-lockable frequency range of 200kHz to 1.5MHz allows for the optimization of efficiency and size.

The LT3467AIDDB# TRPBF includes other features to reduce its size and cost, such as a pulse-skip mode that allows the switching regulator to switch at a lower frequency, with a light load, lowering the operating temperature and increasing efficiency. An internal Soft-Start/Tracker also allows for a smooth, trackable output rise for quick, predictable start-up. An external resistor divider can be used to program the output voltage, which requires very few external components.

The LT3467AIDDB# TRPBF is the ideal solution for applications requiring high-efficiency step-down power conversion between 4V to 28V. With its temperature range, small size, high peak efficiency and a range of features, this component is ideal for automotive, industrial and consumer applications.
