Working Principle

The LT3507AIUHF#TRPBF is a high efficiency, wide input voltage range linear and switching power supply IC. It employs both linear and switching regulation, depending on the application. In linear regulation, the output voltage is proportional to the input voltage. The accuracy of the output voltage depends on the accuracy of the reference voltage and the current sense resistor. This method is used where the variation in output voltage needs to be very small and low noise is required.

In switching regulation, the output is regulated by using a switch-mode power converter. The switching frequency is determined by the pulse width modulation and is usually between 20kHz and 1MHz. This method is used whenever high power efficiency is required. The switching frequencies used in switching regulation can be adjusted as needed to achieve high power efficiency, low noise and also reduce current and EMI emissions.

The LT3507AIUHF#TRPBF IC is designed to operate up to 4-phase in series or parallel. It has an internal low dropout regulator which provides the regulated power to the different outputs. This IC also includes protection features such as over-temperature protection and over-current protection which protect the IC from damage.
