LTC1503CS8-2

LTC1503CS8-2 is a type of DC DC switching regulator designed and manufactured by Linear Technology. It is an integrated switching regulator which provides an easy to implement solution for efficient regulation of step down and step up DC/DC voltage conversion over a wide range of power supply voltages. The LTC1503CS8-2 is capable of delivering up to 0.5A output current from an input voltage of up to 6V. It includes a switching device and an internal voltage reference, eliminating the need for an external reference for most applications. It also includes protection against over current, over temperature and short circuit conditions, as well as a low power shutdown mode.

Application areas

The main application field of LTC1503CS8-2 is in portable and battery-powered devices. It provides a compact, reliable and cost-effective solution for converting a wide range of input voltages to a single regulated output voltage. It is suitable for use in laptop computer power supplies, battery chargers, cell phones and digital cameras. It is also used in automotive applications, such as in audio amplifiers, car stereos and power supplies.

Working principle

The LTC1503CS8-2 is a DC DC switching regulator which is designed to transfer energy from a higher to a lower voltage while regulating the output voltage. This is done by controlling a power switch which is connected to the input voltage and the output voltage. When the power switch is on, energy is transferred from the input to the output and the output voltage is regulated by an internal voltage reference. When the power switch is off, no energy is transferred and the output voltage is maintained.

The LTC1503CS8-2 includes a power switch that can be controlled by an external logic signal or an internal phase-lock loop (PLL) operating at up to 300 kHz. The PLL allows for lower ripple and improved stability. The internal voltage reference is adjustable and provides an output voltage accuracy of ±2%. The LTC1503CS8-2 also provides sense and control pins which allow the regulator to detect and react to changes in the load current. This, in turn, enables the LTC1503CS8-2 to maintain a constant output voltage even under changing load conditions.
