LT8306RS6#TRMPBF

LT8306RS6#TRMPBF is the LT8306 flyback controller IC from Analog Devices (formerly Linear Technology). It’s a high‑voltage, isolated DC–DC controller used to build isolated power supplies. The device drives an external MOSFET and uses a flyback transformer to regulate the output, offering features such as current‑mode control, programmable switching frequency, soft‑start, and protections (overcurrent/short‑circuit, undervoltage, overvoltage/thermal). It supports standby/burst operation for low power and can be used with primary‑side or opto‑feedback schemes for isolation.
Suffix notes:
- RS6 denotes the package type.
- #TRMPBF indicates Tape & Reel packaging with Pb‑free (PbF) assembly.
For exact electrical specifications (input range, duty cycle, switching frequency, startup current, protection thresholds, etc.), please consult the LT8306 datasheet and the packaging table.

LT8306RS6#TRMPBF features (datasheet highlights):
- Primary-side regulated flyback controller for isolated DC-DC power supplies (no optocoupler required in regulation).
- High-voltage start-up and switching MOSFET (integrated or compatible with external FET, depending on variant).
- Current-mode control with slope compensation for stable regulation.
- Programmable switching frequency; supports wide operating ranges.
- Soft-start to limit inrush and output overshoot.
- Robust protection: overcurrent/short-circuit, overvoltage/undervoltage lockout, and overtemperature protection.
- Enable/disable input and fault/status indication.
- Precision reference and feedback for accurate output regulation.
- Designed for high-efficiency operation and low standby power in isolated supplies.
- Automotive/industrial-friendly (robust under harsh conditions; supports PSR feedback without optocoupler).
Note: Exact features/pinout depend on the specific variant and package. For precise specifications, consult the LT8306 datasheet and the RS6/TRMPBF packaging notes.

LT8306RS6#TRMPBF comes in a 16‑pin surface‑mount QFN package (4x4 mm) with an exposed pad; RoHS compliant (PBF).

Pin count: 16 pins.
Function: LT8306RS6#TRMPBF is a 16‑lead, dual high‑voltage synchronous buck/boost DC‑DC controller (two independent channels) that uses external MOSFETs and provides current‑mode control for buck/boost regulation.
