LT1170CT#30PBF DC DC Switching Regulators

The LT1170CT#30PBF is a current-mode switching voltage regulator that can regulate output voltage levels within a wide range of applications. The regulator has a maximum load current rating of 1.5 amps and a maximum output voltage range between 2.85V and 14V. One of its primary features is its ability to accurately maintain an output voltage with little-to-no noise or overshoot. LT1170CT#30PBF is ideal for application in power supplies, battery management systems, and other DC/DC switching regulator applications.

Application field

The LT1170CT#30PBF is suitable for a wide range of DC-DC switching regulator applications, such as power supplies, battery management systems, and power converters.

The regulator can support currents up to 1.5 Amps, making it suitable for applications such as LED lighting, portable electronics, and battery-powered equipment; it can also drive multiple LED’s or groups of LED’s in parallel. Other applications include embedded power supplies in portable devices such as digital cameras, camcorders, hand-held computers, PDAs, and other mobile products.

The LT1170CT#30PBF is also suitable for incorporating synchronous (buck or flyback) or non-synchronous (buck/boost, forward or bridge-chop) energy converters as part of a wide variety of DC/DC switching regulator designs. It can also be used in automotive DC-DC power supplies for airbags, in battery chargers and other power supplies, and anywhere else where a low voltage regulation system is needed.

Working Principle

The LT1170CT#30PBF is a current-mode switching voltage regulator. It works by modulating the voltage across the inductor, allowing the output voltage to be regulated with few-to-no oscillations. A unique feature of the regulator is its ability to maintain steady output voltage levels even when subjected to large step-load transitions.

The LT1170CT#30PBF combines an internal compensation circuit and a high-speed current-mode shaping circuit to minimize the risk of oscillations, while providing accurate voltage regulation. The compensation network provides fast transient response and low ripple.

The regulator also features an internal voltage reference, allowing the user to fine-tune the output voltage setting with a simple two-resistor feedback network. The LT1170CT#30PBF also includes an over-voltage protection circuit as a safety measure to ensure that output voltage remains within the allowed range.

The LT1170CT#30PBF also includes a wide operating voltage range, making it suitable for applications from 2.85V up to 14V. It also features a low quiescent current, allowing the device to be used in battery-powered applications.

In summary, the LT1170CT#30PBF is an ideal choice for a wide range of DC-DC switching regulator applications. Its unique current-mode design makes it well-suited for high-powered applications, and its wide operating voltage range makes it suitable for many battery-powered devices. The regulator’s internal compensation and voltage reference networks make it easy to configure, while the over-voltage protection circuit ensures the output remains within safe limits.
