Product details

Dual 600 mA buck for portable rail generation

The part is aimed at battery-powered handhelds, portable media players, and other gear where two low-voltage rails must be generated from a single Li-ion cell.

Fixed output rails and operating envelope

The two outputs are factory-set to 1.5 V and 1.9 V — there is no adjustable version in this order code.

No official successor part number has been published. For sustainment of existing designs, the remaining inventory in the distribution channel is the primary source. The 0.50 mm ball pitch requires a solder-mask-defined pad and a reflow profile with a peak temperature around 245°C.

Frequently asked questions

How can I order the LM3370TL-3607/NOPB or check stock?

The LM3370TL-3607/NOPB is obsolete, so availability is limited to remaining distributor inventory. Submit an RFQ with your target quantity; we will source it through our network and confirm current pricing and lead time at quote. No stock or price is shown here because figures change daily.

What is the replacement for the LM3370TL-3607/NOPB?

Texas Instruments has not published a direct replacement for this dual-output part. For a single-output alternative with higher current, consider the LM53625LQURNLRQ1 (2.5 A, automotive grade) or the LMR33630APCQRNXRQ1 (3 A, adjustable). Neither is pin-compatible; a board redesign is required.

What are the fixed output voltages of the LM3370TL-3607/NOPB?

The two outputs are fixed at 1.5 V and 1.9 V. There is no adjustable version under this order code.

What package does the LM3370TL-3607/NOPB use?

It comes in a 20-bump WFBGA (20-DSBGA) package, supplied on Tape & Reel or Cut Tape.
