概述
Description
LT3995EMSE#TRPBF is the engineering-sample (EMSE) version of Linear Technology’s LT3995 hot‑swap/current‑limit controller, provided in Pb‑free Tape & Reel packaging for evaluation and design‑in work. The LT3995 family drives an external MOSFET to protect a DC rail during insertion, limits inrush current, and provides protection (OC/UV/OV) with status feedback. EMSE parts are not intended for production use; they’re for early characterization and design verification. The #TRPBF suffix simply denotes Tape & Reel Pb‑Free packaging. Applications include hot‑swap protection for server/backplane power rails and telecom power paths, where you need controlled turn‑on, programmable current limit, and fault indicators.
Note: For production, order the standard LT3995 variant in the appropriate package and packaging.

Features
LT3995EMSE#TRPBF features (concise):
- Quad constant-current LED drivers with a buck-boost regulator
- Wide input voltage range for automotive and portable applications
- Independent current setting and balancing for each LED channel
- Dimming: PWM and analog/dc dimming options
- High efficiency via synchronous topology
- Soft-start and controlled current ramp to minimize inrush
- Protection: overcurrent, overvoltage, short-circuit, overtemperature/thermal shutdown, UVLO
- Fault/status reporting and enable/shutdown control
- External components: needs inductor and current-sense/resistors per channel
- Suitable for multi-string LED backlighting and high-brightness arrays
- Packaging: EMSE with TRPBF (Tape & Reel, RoHS-compliant)
Note: exact current levels, voltage ranges, and pin functionality depend on configuration; consult the LT3995 datasheet for detailed specifications.

Pinout
- Pin count: 8 pins (MSOP-8, EMSE package; TRPBF = Tape & Reel Pb-free)
- Function: LT3995 is a high-voltage, constant‑current LED driver that uses an external N‑MOSFET. It regulates LED current via a sense resistor (IS) and FB feedback, with LX as the switch node to drive the external FET. VIN and GND supply the device, and there are pins to enable/current-limit (EN/ILIM) and dim/dimming control (PWM or DIM). In short: 8-pin LED driver IC for regulation of LED current with external switching MOSFET.
