The concern for greater vehicle safety has increased the number of automotive camera modules that are installed in a vehicle.
The demands on cameras expected to safeguard vehicle safety are relentless.
“Higher resolution (from VGA to 1 or 2 megapixel) in the same size of housing as the previous model or preferably more compact” This is a hurdle for the designers to overcome.
The solution we propose is to “downsize the power supply IC, an indispensable part in an automotive camera.”
ABLIC’s product lineup supports the downsizing and higher performance of automotive camera modules. For example, we provide DC-DC converters in the industry’s smallest class of ultra compact packages or LDO regulator reset ICs with a minimum number of parts.
