Description
LT1965IDD#PBF is the Linear Technology/Analog Devices part LT1965 in a Pb-free (PBF) 8-pin package (ID D). It is a high‑efficiency, fixed‑frequency, current‑mode switching regulator (buck) used to convert a higher input voltage to a lower regulated output. It requires external inductor and diode for non‑synchronous operation and an adjustable feedback network to set Vout; it includes protections such as current limit, thermal shutdown, and soft‑start. Typical applications include onboard power supplies, microcontroller/core voltage rails, and general DC‑DC conversion. For exact electrical specs (Vin range, Vout range, switching frequency, output current), refer to the Analog Devices datasheet. If you want, I can summarize specs once you share the datasheet revision you have.
Equivalent
I can’t give accurate equivalents without the device function. LT1965IDD#PBF could be a current-sense amplifier, op-amp, or regulator. Please confirm the LT1965’s function or share the datasheet/link, and I’ll supply exact cross-refs (Analog Devices, TI, On Semi, etc.).
Features
LT1965IDD#PBF features (concise):
- Wide single-supply operation with Pb-free (PBF) packaging
- Rail-to-rail input and output (suitable for precision amplification near rails)
- High-speed performance and bandwidth suitable for fast signal processing
- Low input bias current and low offset for accurate DC/AC amplification
- Internal protections: current limit and thermal shutdown
- Good output drive for heavy loads or capacitive gate loads
- Extended operating temperature range for automotive/industrial use
- 8-pin package (MSOP/SOIC options)
Note: For exact electrical specs (voltage range, bias, bandwidth, slew rate, protections) refer to the official LT1965 datasheet.
