AIf72y2Q

Mini secondary voltage step-down module - compatible with TO-252-2 pin

Overview

Using DCDC+LDO two-stage voltage reduction, it has the advantages of high efficiency, low heat and low ripple.
Output current 500ma
Compatible with TO-252-2 pin
The actual picture is version V1.2. The latest version, now V1.3, will be tested in the near future.
V1.3: DCDC is replaced with ME3116AM6G , LDO is replaced with ME6210A50M3G
V1.31: Add feedforward capacitor, increase DCDC output capacitance, and optimize wiring again

V1.3 was tested on the board. The 5.0V efficiency is between 0.6-0.7, and the 3.3V efficiency is between 0.5-0.6.

V1.31 re-board test

Efficiency issues with BitBlt
I'm using an ARM920T with a 400M CPU. Bitblt of a 640*480 bitmap takes 0.5ms. It's too slow. The image has a distinct top-down feel. How do you paste bitmaps? Is there a faster method? I have another
