概述
Description
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.
