Here are three compact, low-cost synchronous buck regulators that take up to 16 V in and deliver 5 V at ≥2 A:
Table
| Part Name | Key Specs | Package | Supplier Availability | Links |
|---|---|---|---|---|
| MP1470 | 16 V input, 2 A output, 1.2 MHz switching | TSOT-23-6 | LCSC, Mouser, Digi-Key | Datasheet |
| MP2122AGJ-Z | 4.5–26 V in, dual 2 A channels, 1.5 MHz | QFN-16 | Digi-Key, Arrow, Mouser | Datasheet |
| MP1495SGJ-P | 4.5–16 V in, 3 A output, 500 kHz | SOP-8 | LCSC, Mouser | Datasheet |
Recommendation:
- MP1470 is the simplest and smallest: single-channel 2 A in a tiny TSOT-23.
- MP2122AGJ-Z offers two channels if you’d like to power both 5 V and 3.3 V rails via buck stages, but is larger.
- MP1495SGJ-P provides extra current headroom at a lower switching frequency, easing filter design.
For cost and size, go with MP1470. It’s available for <$1 in volume and fits a minimal footprint.
