Introduction

LT3464ETS8#TRPBF is a DC-DC Switching Regulator from Linear Technology, it is a step-down Switching Regulator designed for automotive applications. It works as either a fixed 4.5V output or as an adjustable output from 0.8V to 5.5V. It features a low quiescent current, high efficiency and wide input voltage range.

Application Field

The LT3464ETS8#TRPBF DC-DC Switching Regulator from Linear Technology is an ideal choice for automotive applications. Due to its wide input voltage range of 4.5V to 30V, it can operate over a wide range of automotive supply voltages. It is perfect for automotive applications that require a low quiescent current, high efficiency, and adjustable or fixed output voltage. It can be used as a backup power supply, as a power supply for a vehicle\'s exterior or interior lights, or as a power supply for many other automotive applications. Additionally, it can be used to drive automotive peripheral circuits such as sensors, CAN and LIN bus transceivers, and Infrared Link transceivers.

Working Principle

The LT3464ETS8#TRPBF DC-DC Switching Regulator from Linear Technology works as either a fixed 4.5V output or as an adjustable output from 0.8V to 5.5V. It employs a current-mode PWM (pulse-width modulation) control operating with a 1.2 MHz switching frequency.When the input voltage is higher than the output voltage, the LT3464ETS8#TRPBF DC-DC Switching Regulator from Linear Technology will start to step-down the voltage. This is achieved by the internal PWM controller switching two power MOSFETs on and off periodically. Between the two MOSFETs, a small inductor and a capacitor are connected, which serves as a low pass filter to obtain a stable DC output.The LT3464ETS8#TRPBF DC-DC Switching Regulator from Linear Technology is also equipped with a number of protection features. These include over-voltage protection, under-voltage lockout, output current limit, and thermal shutdown. These features are very important as they ensure that the regulator as well as its components are not damaged in the event of any unexpected conditions.

Conclusion

The LT3464ETS8#TRPBF DC-DC Switching Regulator from Linear Technology is an ideal choice for automotive applications due to its wide input voltage range and adjustable output voltage. It is designed for low quiescent current and high efficiency. The PWM control works with a 1.2 MHz switching frequency to provide a stable DC output. This device also features a number of protective features to ensure that the regulator and its components remain safe during any unexpected conditions.
