Description

The LT1317BCM8#TR is a versatile and efficient DC/DC converter integrated circuit (IC) from Linear Technology, a company known for its high-performance analog integrated circuits. Designed to meet a wide range of power requirements, this product is ideal for portable and battery-powered applications due to its low voltage operation and high efficiency.

This particular IC is capable of stepping up input voltages from as low as 2.0V and can handle inputs up to 12V, making it suitable for single-cell Li-Ion batteries, multi-cell alkaline or NiMH batteries, or other standard power sources. The LT1317BCM8#TR can provide an adjustable output voltage up to 34V, which is set by a single external resistor, offering flexibility for various design requirements.

The LT1317BCM8#TR operates in a fixed frequency, current mode architecture, which allows for excellent line and load regulation, as well as a predictable output noise that can be easily filtered. The high switching frequency of up to 600kHz enables the use of small, low-cost capacitors and inductors, reducing the overall footprint and component cost of the power supply design.

An important feature of the LT1317BCM8#TR is its low quiescent current, which is crucial for maximizing battery life in portable applications. Additionally, the device includes a low-battery detector, which can be used to signal when the battery voltage falls below a programmable threshold, thus protecting the battery from deep discharge.

The LT1317BCM8#TR is packaged in an 8-lead MSOP, which allows for compact circuit design. It is also available in tape and reel form, denoted by the "#TR" suffix, facilitating automated manufacturing processes. With its robust feature set and flexible design options, the LT1317BCM8#TR is a reliable choice for designers looking to create efficient, space-saving power solutions.
