It keeps switching losses low and avoids the audible band, but it also means the inductor and output capacitor will be physically larger than what you'd use with a 72 kHz part like the ADP1111ANZ-5. If board space is tight and you can tolerate a higher switching frequency, the ADP1111 series runs at 72 kHz and can shrink the passives. But for a retrofit where the existing PCB has a through-hole inductor footprint, the ADP1108AR-5's lower frequency may let you reuse the same magnetics. ## Sourcing and lifecycle — still a current part The ADP1108AR-5 is listed as Active with no NRND or last-time-buy notice. That means it's still in regular production and can be qualified into a new BOM without worrying about an imminent EOL. The RoHS status is non-compliant, so if your assembly line or customer requires RoHS, you'll need to verify the exemption or look at a lead-free alternative like the ADP1111ARZ (adjustable output, surface mount). For RoHS-sensitive builds, check the ADP1111ARZ as a functional alternative — it's also active and surface-mount, but its output is adjustable, not fixed at 5 V.","metaTitle":"ADP1108AR-5 DC-DC Converter, Buck-Boost, 19 kHz, 5 V Fixed","metaDescription":"ADP1108AR-5 step-up/step-down DC-DC converter in SOIC-8, fixed 5 V output, 2 V to 30 V input, 19 kHz switching, active production.
