Description
LT3032EDE#PBF is a dual, high‑efficiency, fixed‑frequency, current‑mode step‑down DC‑DC regulator from Linear Technology (now Analog Devices). It contains two independent buck regulators that share a single input and can generate two adjustable output rails. Key features: per‑channel enable, soft‑start, current limit, thermal protection, and external resistor‑settable outputs; designed for fast transient response and high efficiency. The EDE suffix denotes the package option (16‑lead with exposed pad); #PBF indicates Pb‑free, RoHS‑compliant packaging. Typical uses include multi‑rail power for CPUs/FPGA/memory and other battery‑powered digital systems. For exact specs (input range, max current per channel, switching frequency), consult the datasheet.
Features
Here are the typical features of the LT3032EDE#PBF (datasheet-basis, concise):
- 3 A adjustable low-dropout linear regulator
- Enable/disable control pin
- Current limit and thermal shutdown for protection
- Reverse current protection (input–output protection)
- Remote sense capability for accurate regulation
- Adjustable output via external resistor network
- Wide input voltage range with robust overvoltage protection
- Short-circuit and overload protection
- Low quiescent current when off
- Pb-free, RoHS-compliant packaging (EDE, 8-pin) #PBF
Note: exact numbers (dropout, input range, voltage accuracy) are in the datasheet; this summarizes the core features.
