Application Field

The LT1172HVIQ#TRPBF is suitable for a range of applications ranging from automotive, telecom and industrial activities to consumer applications. It can be used in battery powered applications, including handhelds and notebook computers. It is particularly well-suited for automotive and industrial applications, due to its wide input voltage range and low standby current. With external resistors and capacitors, it can also be configured for step-up, step-down, and inverting DC/DC converter functions.

It is easy to use and requires minimal external components, which reduces the overall bill of materials and time-to-market of the end product. Furthermore, the LT1172HVIQ#TRPBF supports output voltages of up to 60V and delivers over 95% efficiency, making it ideal for high output power applications.

Working principle

The LT1172HVIQ#TRPBF is a current-mode DC/DC converter with a wide input voltage range of 2.7 V to 60 V. It utilizes an internal power switch and an internal 0.85V reference voltage to provide constant current to the inductor, allowing it to be operated at very high frequencies while still providing regulation and low outputs. The internal current limit and the feedback loop ensure that the output voltage remains constant over a wide range of load conditions. It includes output over-voltage, over-temperature and current limit protection features to prevent over current conditions in the event of a fault.

The LT1172HVIQ#TRPBF has a very low quiescent current of less than 10 μA, making it ideal for applications which require high efficiency and long battery life. Furthermore, its wide operating range, high efficiency, small form factor and very low output voltage ripple make it well suited for low-power applications.

In short, the LT1172HVIQ#TRPBF is an efficient and cost-effective DC/DC switching regulator designed for a wide range of applications, making it an ideal solution for providing regulated voltage outputs in automotive, telecommunication and industrial systems. Its wide input voltage range, high efficiency, small size and low output voltage ripple make it a great choice for both automotive and industrial applications.
