Product details

Dual 600 mA rails at 2 MHz — what the fixed outputs mean for your BOM

The LM3370SDX-3416/NOPB is a dual-channel synchronous buck regulator from Texas Instruments, delivering fixed 1.4V and 2.8V outputs at 600 mA each from a 2.7V to 5.5V input rail.

Fixed output voltages — no adjustment possible

The output configuration is positive and fixed — channel 1 is regulated to 1.4V, channel 2 to 2.8V. There is no feedback pin for external resistor divider adjustment. If your design needs a different voltage on either rail, this part will not fit without a post-regulator or a different regulator IC.

Temperature range and package — board-fit checklist

Operating temperature is -30°C to 85°C, which covers most indoor and light industrial environments but not -40°C automotive cold-crank or extended outdoor telecom. The supplier device package is 16-WSON (5x4).

If you need a drop-in replacement, check the LM3370 family for pin-compatible fixed-output variants that may still be active.

Frequently asked questions

Is LM3370SDX-3416/NOPB obsolete?

Yes, the product status is listed as obsolete. Sourcing is through independent distribution against an RFQ.

What are the fixed output voltages?

The outputs are fixed at 1.4V on channel 1 and 2.8V on channel 2. There is no adjustment via external resistors — if your design needs different voltages, this part will not work without a post-regulator.
