Switching regulator that steps voltage down efficiently. Needs an inductor.
How it looks
Real image: CORE3588, rendered by KiCad from our board file
A buck converter on CORE3588, 12 x 12 mm: it turns the system rail into 3.3 V for the six cameras. A second one (U3, L2) makes PERIPH_3V3 just below it.
1U2, the TLV62569 switching chip (SOT-23-5).
2L1, the 2.2 uH inductor (coil): the part every buck needs.
3C8, 10 uF: smooths the input.
4C9 and C10, 10 uF each: smooth the output, CAM_3V3 for the cameras.
How it works
Where it fits
A buck steps down; a boost converter steps up; a buck-boost does both. Its input needs a bulk cap, and the switching makes noise, so placement is tight.
