The LT
The LT8301 is a micropower isolated flyback converter designed to sample the isolated output voltage directly from the primary-side flyback waveform. This architecture eliminates the need for a third winding or an opto-isolator for regulation, simplifying the design and reducing component count.
| Input Voltage Range | 2.7V to 42V |
|---|---|
| Output Power | 6W |
| Switch Current Limit | 1.2A |
| Package Type | 5-lead ThinSOT package |
| Quiescent Current (Sleep Mode) | 100µA |
No, it samples the isolated output voltage directly from the primary-side flyback waveform.
The output voltage is programmed with a single external resistor connected to the RFB pin.
