Key Features
- Current-mode PWM flyback controller with 4.5 V to 80 V input range and 860 kHz switching frequency enables compact transformer design in isolated industrial power supplies
- Wide 4.5 V to 80 V input voltage range supports automotive 12 V, 24 V, and 48 V bus standards plus high-voltage industrial rails in a single controller IC
- 20-pin TSSOP with exposed pad provides efficient thermal dissipation for the gate driver and control circuitry in space-constrained flyback converter designs
Applications
LT8714EFE#PBF is used in industrial power supplies, automotive DC-DC converters, and telecommunications equipment that require isolated or non-isolated flyback regulation from input voltages up to 80 V. Its 860 kHz switching frequency allows the use of smaller flyback transformers and output capacitors, reducing overall converter size in 12 V to 48 V bus-powered modules. The wide input range makes it suitable for automotive systems where the supply can vary from 4.5 V during cold crank to 80 V load-dump transients.

Frequently Asked Questions
What input voltage range does LT8714EFE#PBF support, and which bus standards does this cover?
LT8714EFE#PBF operates from 4.5 V to 80 V input, covering automotive 12 V and 24 V buses, 48 V telecom and automotive mild-hybrid rails, and industrial 60 V or 72 V supplies. The 80 V maximum also accommodates load-dump transients in 12 V automotive systems, which can spike to 60–80 V under fault conditions.
How does the 860 kHz switching frequency of LT8714EFE#PBF benefit flyback transformer selection?
At 860 kHz, LT8714EFE#PBF allows the flyback transformer core to be significantly smaller than designs switching at 100–200 kHz, because the volt-second product per switching cycle is reduced by a factor of 4 to 8. This reduces transformer height and footprint in space-constrained 12 V to 48 V isolated power supply modules.
What control mode does LT8714EFE#PBF use, and how does current-mode control improve flyback performance?
LT8714EFE#PBF uses current-mode PWM control, which senses the peak inductor current each cycle and provides inherent cycle-by-cycle current limiting. This simplifies loop compensation, improves line transient rejection, and protects the flyback transformer from saturation during output short-circuit events, reducing the need for over-current protection circuits.
In what scenarios would LT8714EFE#PBF be selected over a lower-frequency flyback controller for an automotive 48 V application?
LT8714EFE#PBF is preferred in 48 V automotive applications where board space is limited, because its 860 kHz switching frequency reduces transformer core volume by approximately 4× compared to a 200 kHz controller. The 80 V input rating also provides the margin needed to withstand 48 V system load-dump pulses, which can reach 60–80 V in mild-hybrid vehicles.
