Descripción general

Description

MAX1682EUK+T is a Maxim Integrated switching regulator/LED-driver IC. It is a compact, high‑efficiency device with a fixed‑frequency, current‑mode controller and an integrated switch to implement a buck/boost DC‑DC converter for constant‑current LED driving and general power conversion.
Key points:
- Integrated power switch and current‑mode control for high efficiency
- Constant‑current output for LEDs (via external sense resistor)
- PWM dimming and protection features (undervoltage lockout, current limit, thermal shutdown)
- Suffixes: EUK indicates a RoHS package variant; +T denotes Tape & Reel packaging
- Common uses: portable power supplies, LED backlighting, automotive lighting, compact DC‑DC applications
For exact electrical specs (input range, output current, switching frequency, dimming interface), consult the MAX1682 datasheet and ordering information.

Features

MAX1682EUK+T is a Maxim LED backlight driver. Key features include:
- Integrated boost regulator with a power MOSFET to drive LED strings
- External sense resistor for precise constant-current LED drive
- Dimming options: PWM dimming and/or analog brightness control
- Wide input range suitable for battery or 3.3V supplies
- Fixed-frequency, current-mode control for stable regulation
- Soft-start to suppress inrush
- Enable/shutdown control
- Protections: undervoltage lockout, overcurrent/short-circuit protection, thermal shutdown
- Small package; Tape & Reel version indicated by +T (MAX1682EUK+T)
Note: +T denotes tape-and-reel packaging.

Package

16-pin SSOP (SO-16) package, RoHS, with Tape‑and‑Reel option (+T).

Pinout
