Product details

Boost LED driver for two-channel backlight — what the ratings mean

The LM3502ITL-16/NOPB is a DC-DC boost regulator with integrated switch, designed to drive two LED strings for backlight applications. The 16 V output ceiling allows series strings of up to four white LEDs per channel, depending on forward voltage. The 400 mA switch current rating sets the total power budget — at 16 V out, the maximum deliverable power is about 6.4 W before the switch limits, though the actual LED current per channel depends on the inductor and sense resistor. PWM dimming input is on the enable pin; the 1 MHz switching frequency keeps the inductor small — typically 4.7 µH to 10 µH — which helps fit the 10-TµSMD (1.9x2.07 mm) package on a compact display PCB.

Because the part is obsolete, it is not stocked in volume by franchised distributors.

Package and footprint — 10-TµSMD layout notes

The 10-TµSMD (1.9x2.07 mm) package is a wafer-level chip-scale package — the solder balls are the only pads.

Frequently asked questions

How can I order the LM3502ITL-16/NOPB or check availability?

The LM3502ITL-16/NOPB is obsolete and not held in franchised distributor stock. We source it through our independent supply chain — submit an RFQ with your target quantity and price, and we will confirm availability and current pricing at quote time. No stock-holding claim is made on this page.

Is the LM3502ITL-16/NOPB a direct replacement for the LM2703MF-ADJ/NOPB?

No. The LM2703MF-ADJ/NOPB is a single-output boost regulator with 0.35 A switch current and adjustable output voltage, while the LM3502ITL-16/NOPB has two outputs and a fixed 16 V rail. The package and pinout differ — a board layout change is required.

What is the dimming method of the LM3502ITL-16/NOPB?

PWM dimming is supported via the enable pin. The PWM signal directly modulates the switching activity, giving a wide dimming ratio without audible noise from the inductor.

Where can I find the datasheet for the LM3502ITL-16/NOPB?

The Texas Instruments product page for base number LM3502 hosts the datasheet. The document covers the full electrical characteristics, application circuits, and layout guidelines for the 10-TµSMD package.
