TPS92023DR

TPS92023DR is Texas Instruments’ three-channel constant-current LED driver IC. It is intended to drive multiple LED strings with regulated current, suitable for backlighting, signage, and general lighting.
Key features (typical):
- Three independent current sinks with programmable string current via external resistors.
- Dimming options through PWM or analog control signals.
- Protections: overcurrent/short-circuit protection, undervoltage/overvoltage protection, and thermal safeguards.
- Lightweight external component needs (few resistors and capacitors) for compact, low-cost lighting solutions.
Packaging and variant:
- DR suffix indicates TI’s device/package/tape-and-reel variant; check datasheet for exact package and ordering options.
Applications:
- LED backlighting for displays, architectural/retail lighting, and multi-string LED lighting where separate strings need coordinated current.
For exact electrical specs (input voltage range, current per channel, dimming frequency, etc.), consult the TPS92023DR datasheet and TI product page.

- Pin count: 8 pins (8-pin package)
- Function: Constant-current LED driver for a single LED string; regulates LED current via an external sense resistor and includes enable/open-load protection (suitable for low-voltage LED applications).

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: TI is an American multinational semiconductor design and manufacturing company, specializing in analog and embedded processing ICs, sensors, and related technologies, headquartered in Dallas, Texas.

TPS92023DR is a high-efficiency constant-current LED driver. Typical application areas include:
- LCD backlight modules for TVs/monitors and notebook displays
- Signage and billboard illumination
- Architectural and decorative lighting with multiple LED strings
- Automotive lighting (interior/exterior) requiring reliable current regulation and dimming
It supports dimming (PWM/analog) and drives LED strings with stable current for compact, low-power lighting solutions.

TPS92023DR comes in a 6‑pin SC-70 (D‑package) with Tape & Reel packaging; -DR denotes the Tape‑and‑Reel variant.
