概述
Description
LTC7150SIY#PBF is the Pb-free version of Linear Technology/Analog Devices’ LTC7150, a high‑voltage, isolated switching-regulator controller intended for isolated DC–DC power supplies (e.g., flyback/topology).
What it does:
- Provides the control signals to drive a high‑voltage primary switch in an isolated converter.
- Supports typical PSR/applications with optional feedback via optocoupler, depending on design.
Key features (typical):
- Wide input voltage range and high‑voltage operation
- Control modes (often current‑mode) with programmable switching frequency
- Soft‑start, overcurrent/short‑circuit protection, undervoltage lockout
- Thermal protection and other protective functions
Packages and suffix:
- SIY is the package code; #PBF indicates Pb‑free assembly.
Where to use:
- Isolated power supplies for telecom, industrial, data‑center, and embedded systems.
Note:
- For exact pinout, electrical specs, and application notes, consult the LTC7150 datasheet and product page.
