Overview

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.).

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing integrated circuits sold worldwide.

Application

Applications for LM5157RTER (wide-input, high-efficiency DC-DC controller, often used in buck/boost regulators):
- Automotive power management (12–60 V bus)
- Industrial DC-DC supplies and motor-control power stages
- Telecom/datacom line cards and servers for stable rails
- Point-of-load regulators for CPUs/FPGA/ASICs
- Battery-powered systems needing buck-boost regulation
- General wide-input DC-DC conversion with high efficiency
