Additional Details

The LT3470ITS8 utilizes a constant frequency, current mode architecture. It operates from an input voltage range of 0.7V to 5.5V. The 1.2MHz switching frequency allows for the use of small, low-profile inductors and capacitors. The integrated Schottky diode reduces external component count and improves efficiency. The low quiescent current minimizes power consumption in standby mode, further extending battery life. The LT3470ITS8 provides overvoltage protection and short-circuit protection. The small TSOT-23 package makes it ideal for portable and space-constrained applications.
