Product details

Dual 600 mA synchronous buck — fixed rails, small footprint

The LM3370TLX-3022/NOPB is a dual-output synchronous step-down (buck) regulator from Texas Instruments, delivering fixed 1.2V and 1.85V rails at up to 600 mA each from a 2.7V to 5.5V input supply. Switching at 2 MHz, it lets you use small inductors and ceramic caps, keeping the total solution compact — a good fit for space-constrained portable or embedded designs.

Obsolete — plan your BOM move now

If you are supporting an existing design, source remaining stock through independent distribution. For new designs, evaluate a current-generation dual buck regulator with similar input range and output current.

Package and temperature — field-fit realities

Housed in a 20-WFBGA (DSBGA) package, this is a fine-pitch BGA — rework on site without a hot-air station is risky.

Frequently asked questions

How can I order the LM3370TLX-3022/NOPB or check availability?

The LM3370TLX-3022/NOPB is obsolete (Texas Instruments no longer manufactures it). We can source remaining inventory from our independent supply chain — submit an RFQ with your target quantity and we will confirm availability and pricing at quote time.

What is a direct replacement for the LM3370TLX-3022/NOPB?

Texas Instruments does not list a direct pin-compatible replacement. For new designs, consider a current dual buck regulator such as the LM53625 (single output, 2.5A) or LMR33630 (single output, 3A) — these are automotive-grade but have different output counts and packages, so a board layout change is required.
