Product details

Eight-channel charge-pump LED driver for backlight

The LM3535TMX/NOPB from Texas Instruments is a switched-capacitor (charge pump) DC-DC regulator that drives up to eight LED strings at 25 mA per channel, intended for backlight applications. Dimming is controlled via PWM, and the internal switches are integrated, so no external FETs are needed for the boost or current regulation.

Package and temperature grade

Rated for -30°C to +85°C ambient (TA), it covers most consumer and industrial backlight environments but is not specified for automotive-grade extended temperature. The 25 mA per-channel current is a typical backlight drive level for small- to medium-size LCD panels; with eight outputs, the total LED current budget is 200 mA, shared across the strings.

Frequently asked questions

What is LM3535TMX/NOPB's listed type and dimming method?

The device is a DC DC Regulator (charge pump topology) with PWM dimming control, designed for backlight applications.

Does LM3535TMX/NOPB drop in as a replacement for TLC69611RTWR?

No — the TLC69611RTWR is a linear LED driver with 16 outputs at 60 mA per channel and no internal charge pump. The LM3535TMX/NOPB uses a switched-capacitor topology, different output count (8 vs 16), and lower per-channel current (25 mA vs 60 mA). They are not drop-in replacements; the board topology and BOM would need rework.
