PT6305 series is a 3-amp high-performance adjustable ISR with a static voltage tolerance of 3.2-3.4V, a switching frequency of 500-800KHz, a working voltage range of 4.5-9V, an output current range of 0.3-3.0A, and an efficiency of 80-85%
The document describes the PT6305 Series, an integrated switching regulator (ISR) designed to provide +3.3V output from a +5V input system. The series includes variants for different voltage outputs (+1.8V, +2.1V, and +1.2V). Key features include 85% efficiency at 1.5A load, internal short circuit protection, over-temperature protection, and operation with only one external capacitor.
