Working Principle

The LTC3261IMSE#PBF is based on a self-oscillating synchronous buck regulator topology. The regulator has a wide input voltage range and can operate with an input voltage as low as 2.7V and as high as 60V. The input voltage is regulated by an internal high side and low side MOSFETs. The power is then transferred from the input voltage to the output voltage via a synchronous rectifying process, reducing the reverse current losses and providing a higher efficiency.The output voltage of the regulator is regulated by the current mode control scheme, which provides fast dynamic load transient response and excellent line regulation. Additionally, the LTC3261IMSE#PBF also has built in soft start feature, thermal shutdown protection and overvoltage protection to ensure safe operation of the device.
