| FFF Compatibility | The part shares the identical 10-pin MicroSiP (uSiL) footprint and pinout layout with the original.The physical dimensions (2.5mm x 2.0mm x 1.1mm) are exactly the same as the original.It performs the exact same electrical function in forced-PWM mode and has a higher maximum output current rating of 2A. | The pinout and land pattern match the original 10-pin MicroSiP layout exactly.The physical package dimensions are identical at 2.5mm x 2.0mm x 1.1mm.It automatically switches to power save mode (PFM) under light loads, which differs from the forced-PWM low-noise mode of the original. | ||
 AI Summary | TPSM82821ASILR by Texas Instruments: Non-Isolated PoL Module DC DC Converter 1 Output 0.6 ~ 4V 1A 2.4V - 5.5V Input. | This is the ideal drop-in alternative. It uses the exact same package and pinout, runs in the same forced-PWM mode to minimize output voltage ripple, and offers a higher maximum current capability of 2A for extra safety headroom.
| This sibling is identical in footprint and physical package size, but it features automatic Power Save Mode (PFM) instead of forced-PWM under light loads. This increases light-load efficiency but may introduce variable switching frequency noise.
