The Power Integrations LYT2004D-TL is an isolated offline Flyback switcher from the LYTSwitch™-2 series with an integrated internal switch. It offers a 725V breakdown rating, 85kHz switching frequency, 55% maximum duty cycle, and delivers up to 8 W. Housed in an 8-SOIC (7 leads) package and rated for -40°C to 150°C (TJ), it is well suited to compact, thermally demanding low-power AC-DC designs.
- 725V breakdown rating — provides strong offline mains margin.
- Integrated switch — reduces external component count and simplifies layout.
- Compact 8-SOIC package — saves board space.
- Wide -40°C to 150°C (TJ) range — reliable in high-temperature enclosures.
- 8 W output — ideal for low-power isolated supplies.
Low-Power Isolated Supplies
With 8 W output and 725V breakdown, the LYT2004D-TL suits compact isolated flyback supplies for small appliances and standby rails.
High-Temperature Enclosures
A -40°C to 150°C (TJ) rating supports reliable operation in thermally demanding, enclosed designs.
Space-Constrained Boards
The 8-SOIC (7 leads) package and integrated switch reduce footprint in compact power stages.
Efficient Low-Power Conversion
An 85kHz switching frequency and 55% maximum duty cycle support efficient low-power flyback operation.
