AP63205WU-7

AP63205WU-7 is a Diodes Incorporated synchronous step-down buck converter in TSOT-26, supplied on a 3,000-piece tape and reel (the -7 code) — a fixed 5.0 V rail from a 3.8 to 32 V input for industrial controllers, USB power stages and distributed point-of-load conversion. It is the 5 V sibling of the AP63203WU-7 on this site: same package and the same switching platform, with the feedback reference held in continuous-conduction mode to 4.95 V minimum, 5.00 V typical and 5.05 V maximum — a ±1% window on the 5 V rail without an external divider. The PWM frequency is 1.1 MHz typical with ±6% spread-spectrum dithering, and light loads move to pulse-frequency modulation rather than holding a fixed frequency. Quiescent current is 22 µA typical. The selection point over the 3.3 V sibling is simply the rail voltage — the two codes are not interchangeable on a qualified BOM. Selection advice: the high-side peak current limit is 2.5 A minimum, 2.8 A typical and 3.1 A maximum, and continuous output sits below that limit at high duty cycles; the 3.8 V input floor is an operating range, not a regulation promise from an input below the 5 V rail — check the datasheet curves for your input-output pair. WU is the TSOT-26 package code; match the full code including the -7 reel suffix. No current lifecycle status was verified for this code in this review, so none is claimed here — supply is confirmed per order against the exact code. Parameters verified against the Diodes DS41326 Rev. 3-2 datasheet.
