Product Overview: LTC1174HVCN8-3.3#PBF

The LTC1174HVCN8-3.3#PBF is a high-performance, step-down switching regulator from Analog Devices Inc. Designed to deliver a fixed output voltage of 3.3V, this regulator is capable of driving a 1.5A load with excellent line and load regulation. The device comes in an 8-lead PDIP package, ensuring ease of integration into a wide range of electronic applications.

One of the key features of the LTC1174HVCN8-3.3#PBF is its high efficiency, which can reach up to 90%. This makes it an ideal choice for battery-powered systems where power conservation is critical. The regulator operates at a switching frequency of 100kHz, which provides a good balance between efficiency and component size, allowing for the use of smaller, less expensive inductors and capacitors.

The device incorporates several protective features to ensure reliability and durability in demanding environments. These include thermal shutdown, which prevents damage from overheating, and current limiting, which protects the device and the load from excessive current draw. Additionally, the LTC1174HVCN8-3.3#PBF includes a low-battery detector that can signal when the input voltage falls below a preset threshold, which is particularly useful for battery-operated devices.

Another advantage of this regulator is its Burst Mode® operation, which significantly reduces quiescent current during light loads or standby, thus extending battery life in portable applications. The LTC1174HVCN8-3.3#PBF also features a shutdown mode that reduces the supply current to 10μA, providing further power conservation when the device is not in active use.

Engineers will appreciate the ease of use provided by the LTC1174HVCN8-3.3#PBF. With minimal external components required, this regulator allows for a compact and cost-effective power solution. The device's robust design and comprehensive feature set make it well-suited for a variety of applications, including portable computers, handheld instruments, and other portable devices that require efficient power management.

In summary, the LTC1174HVCN8-3.3#PBF from Analog Devices Inc. is a versatile and efficient step-down switching regulator that offers a fixed 3.3V output, high efficiency, protective features, and low-power operation modes, making it an excellent choice for designers looking to optimize power consumption in their electronic products.
