The LT1173CN8-5#PBF is suitable for many applications and offers a number of features that make it a viable option for those looking for reliable power management.

Application fields

The LT1173CN8-5#PBF is well suited for a variety of applications, including computers, consumer electronics, portable devices, instrumentation and battery-clamp applications. It operates at a wide input voltage range, from 5V to 40V, with a maximum output current of 1A and a maximum output voltage of 16V. The LT1173CN8-5#PBF can also step-up or step-down the input voltage, providing it with exceptional flexibility.

Additionally, the LT1173CN8-5#PBF is designed to provide high efficiency with low power consumption. Its synchronous rectification and high switching frequency reduce power losses, while its high efficiency protects against short-circuit and current-limit conditions. The LT1173CN8-5#PBF is also designed to work over a wide temperature range, enabling it to handle tough environmental conditions.

The LT1173CN8-5#PBF is also compatible with a wide range of microcontrollers, making it well suited for use in embedded systems. Its integrated protection and current-limit features provide exceptional safety, while its wide input and output range make it suitable for applications that require both a high and a low output voltage. Furthermore, its pin-programmable features allow the user to customize the device to the exact requirements.

Working principle

The LT1173CN8-5#PBF consists of a basic buck-boost regulator, which uses a voltage reference as the regulating element, as well as several other integrated components including a low dropout regulator IC, a low noise ripple filter, and several complementary components. The buck-boost regulator receives power from the input voltage and outputs a voltage less than or equal to the input voltage, depending on the output current required.

The LT1173CN8-5#PBF also incorporates a synchronous rectifier circuit that improves efficiency by using the inductor current to deliver power to the output, instead of the voltage reference. This helps to reduce the power consumed by the regulator, while also providing a low noise output ripple. Additionally, the LT1173CN8-5#PBF also features integrated current limit and short-circuit protection, to help ensure reliable operation.

The LT1173CN8-5#PBF also features a pin-programmable interface, which allows the user to configure the operation of the regulator, by changing the functions of certain pins. The most common pin-programmable features are the enable pin, to control the enable/disable mode, and the voltage reference pin, to control the reference voltage. This provides the user with the ability to customize the performance of the device, without having to make any hardware changes.

Conclusion

The LT1173CN8-5#PBF is a reliable and efficient voltage regulator, suitable for use in a wide range of applications. Its wide input and output range make it ideal for use in battery-clamp, computers, portable devices, or instrumentation applications. Its integrated protection and current-limit features provide enhanced safety and reliability, while its synchronous rectification and low noise ripple filter provide for exceptional efficiency. Additionally, its pin-programmable features allow the user to customize the device to specific requirements, making it a great choice for those in need of reliable power management.
