Key Features
- No-optocoupler isolated flyback topology with internal 65V/4.5A power switch simplifies isolated power supply design and reduces BOM cost
- Wide 3V to 42V input voltage range with current-mode resonant control for high efficiency across automotive, industrial, and telecom supply rails
- Micropower quiescent current under 100 µA enables ultra-low standby power in battery-backed and energy-harvesting applications
Applications
The LT8302HS8E#PBF is ideal for isolated auxiliary power supplies in industrial field instruments, telecom line cards, and motor drive gate driver supplies where optocoupler-free feedback simplifies isolation barrier design. Its wide 3 V to 42 V input range accommodates automotive 12 V/24 V rails and industrial 24 V/48 V buses. The micropower operating mode also suits energy-harvesting nodes and battery-powered remote sensors requiring isolated 5 V or 12 V outputs.

Frequently Asked Questions
What is the input voltage range and internal switch rating of the LT8302HS8E#PBF flyback converter?
The LT8302HS8E#PBF accepts input voltages from 3 V to 42 V and integrates a 65 V / 4.5 A internal power switch. This wide input range lets a single design cover 5 V USB, 12 V automotive, and 24 V to 36 V industrial rails without changing the external transformer, greatly simplifying supply chain management.
How does the LT8302HS8E#PBF eliminate the need for an optocoupler in an isolated flyback design?
The LT8302HS8E#PBF uses a primary-side regulation scheme based on current-mode resonant control and transformer magnetizing inductance sensing, removing the need for a secondary-side optocoupler and reference IC. This reduces component count by at least 3 parts, shrinks isolation barrier area, and improves reliability since optocouplers degrade over time at temperatures above 85°C.
Which industrial or automotive supply rails are best served by the LT8302HS8E#PBF?
With a 3 V to 42 V input range and current-mode control, the LT8302HS8E#PBF serves 12 V automotive ECU auxiliary supplies, 24 V PLC isolated sensor rails, and 36 V to 42 V forklift or battery-backup systems. Its 65 V switch rating provides sufficient headroom for 42 V load-dump transients common in 12 V automotive environments.
What package does the LT8302HS8E#PBF use and how does it affect thermal management?
The LT8302HS8E#PBF is housed in an 8-pin SOIC package (5.28 mm x 5.28 mm body). While compact, the SOIC-8 exposed pad variant can dissipate several hundred milliwatts with a proper thermal via array under the pad. For continuous output power above 1 W, designers should add copper pours or external heatsinking to keep junction temperature below 125°C over the full -40°C to 125°C operating range.
