I did some more digging and seems the high-ripple I see on VOUT is due to control-loop dynamics.
While throwing the schematic together I totally ignored the loop gain-VS-freq behaviour.
By adding couple of caps experimentally (w/o calculating transfer-function or phase-margin) around the...
I'm trying to simulate a purely hysteretic converter in LTSpice (no one-shots used).
I used an Op-Amp block w feedback resistors to make a hysteretic comparator, the hysteresis is about 20mV.
The OpAmp drives a PMOS and 0.4V shottky is used for the catch-diode.
On VOUT there is inductor and cap...
Does anyone know a simple microcontroller/chip that can interface to a Image-Sensor and TFT LCD-module?
There is no need for capturing images or video, just forward live camera output directly to the LCD screen for viewing. Full blown Apps Processors like OMAP maybe an overkill, so looking for...
Looking to interface between simple VGA sensor (YUV output) and an LCD module which accepts RGB input. No image capture required. Just send live image from Image Sensor to LCD.
One caveat is that most sensors and some LCDs have I2C or SPI interfaces and require several configuration commands...
