LT1534IS#PBF

PMIC - Voltage Regulators - DC DC Switching Regulators

The LT1534IS#PBF is an integrated circuit, used for voltage regulation. It works as a type of DC DC switching regulator, with a maximum output current of 2.5A, and is available in a range of voltage inputs and outputs, such as 1.2V to 4.5V and 5V to 18V. It has a wide operating range and low quiescent current consumption, making it ideal for low power applications.

The LT1534IS#PBF operates in a voltage-mode control scheme, in which the output voltage is compared to a reference voltage. The device is then capable of adjusting the switching frequency to reach the desired output voltage. It also has a 1GHz bandwidth, allowing fast adjustments to the voltage. This results in high efficiency, up to 97%, for a wide range of input and output voltages.

The LT1534IS#PBF is most commonly used in low power applications, such as battery-powered equipment, and portable electronic devices. It is also suitable for AD converters, cellular base stations and RF transceivers. It offers low output voltage ripple and very low noise, meaning it can be used to provide clean power for sensitive electronic devices.

The LT1534IS#PBF is also capable of being configured to operate as a current-mode switching regulator. This allows the device to respond faster to changes in load current, resulting in improved transient response. It also provides reliable operation at low load currents, as well as higher currents.

In addition to its wide range of operating parameters, the LT1534IS#PBF has a built-in thermal protection feature. This protects the device from thermal failure, as a result of high temperatures or prolonged use. The device also contains an internal soft-start feature, which helps to reduce inrush current when the device is turned on.

Overall, the LT1534IS#PBF is a versatile, high-performance voltage regulator. It is ideal for low power applications, where high efficiency and low noise are key requirements. It is capable of responding quickly to input and output changes, and includes built-in features for protection.
