概要
Description
LM5157RTER is a Texas Instruments part: the LM5157 family is a high‑efficiency constant‑current LED driver/controller that can operate from a wide input voltage using a buck/boost topology to regulate LED current. The RTER suffix denotes packaging for tape-and-reel (reel delivery for automated assembly). It’s used for automotive and general lighting to drive LED strings with adjustable current, offering dimming options (analog/PWM) and protections (UVLO, overcurrent, LED open/short, thermal). The external components typically include an inductor, diode, current-sense resistor, and a MOSFET (external or integrated depending on variant). For exact electrical specs, pinout, and application circuits, consult the TI LM5157RTER datasheet and TI application notes. If you share your application details (LED count, supply range, dimming method), I can summarize the exact numbers from the datasheet.
Package
LM5157RTER is in an 8‑pin VSSOP package (VSSOP‑8, about 3.0 × 3.0 mm). The TER suffix indicates Tape & Reel packaging.
Pinout
- Pin count: 8 pins (8-pin package, e.g., SOIC-8/TSSOP-8).
- Function: LM5157RTER is a DC-DC converter controller for buck/boost regulation, typically used with external MOSFETs to implement a high-efficiency switching regulator (provides current‑mode control, feedback/compensation, enable, etc.).
