By sampling the isolated output voltage directly from the primary side flyback waveform, the module requires no opto-isolator or third winding for regulation.
The converter operates over a 2.8 to 42V input voltage range, has a 3.6A/65V power switch and delivers up to 15W of output power, making it well suited for a variety of industrial, medical, datacom, military and automotive applications.
The LT8302 operates in boundary mode, which is a variable frequency current mode control switching scheme typically resulting in +/-5% regulation over the full line, load and temperature range.
Boundary mode enables the use of a smaller transformer compared to equivalent continuous conduction mode designs.
Additional features include output short circuit protection, a 380µA no load quiescent current with the output voltage in regulation, internal soft start and compensation, along with output diode temperature compensation.
