Übersicht

Description

The TLC7135CDW is a compact constant‑current LED driver IC (8‑pin package) used to drive LED strings from a higher voltage supply. It regulates the current through the LEDs with a value set by an external resistor, providing stable brightness independent of supply variations. It typically includes protections such as short/open LED detection and thermal shutdown, and it supports dimming (e.g., via a control/PWM input). Common applications include LED backlighting, indicator LEDs, and small LED lighting where a reliable current source is preferred over a raw voltage drive. For exact current ranges, voltage limits, protection details, dimming behavior, and pinout, refer to the official TLC7135CDW datasheet.

Features

TLC7135CDW features (concise):
- 3-channel constant-current sinks for LED strings
- One external resistor sets the current for all three channels
- Temperature-compensated current regulation for stable brightness
- Protection: overcurrent, short-circuit, and thermal shutdown
- Suitable for low-voltage sources (e.g., single-cell Li‑ion) and LED arrays
- High efficiency with low quiescent current
- Intended for compact, easy-to-use LED driver applications
- Small CDW package suitable for compact designs
Note: exact current ranges and input voltage specs depend on the specific device variant; consult the datasheet for precise numbers.

Package

8-pin SOIC (DW) package.

Pinout

- Pin count: 8 pins (8-pin package, CDW suffix).
- Function: A linear constant-current LED driver/regulator. It provides a fixed LED current (≈350 mA) set by an external resistor, to drive a string of LEDs from a higher supply.

Manufacturer

Manufacturer: Texas Instruments (TI).
What kind of company: TI is an American multinational semiconductor company that designs and manufactures analog and digital integrated circuits and other electronics components.

Application

TLC7135CDW is a constant-current LED driver IC. Typical applications:
- Battery-powered LED strings (single-cell sources)
- Flashlights/torches
- Indicator and backlight LEDs in handheld electronics (LCDs/keypads)
- Small signage and portable lighting
Provides regulated current with a simple external resistor; suitable for compact, low-voltage LED drive.

Equivalent

Closest cross-reference: AMC7135 (350 mA constant-current LED driver). TLC7135 is part of the 7135 family, so other vendors’ 7135 variants with the same function and similar pinout can substitute. Always verify current-setting resistor, package, and pinout when replacing.
