Description
The YB1517 is a Current-mode PWM step-up DC-DC converter.
It can drive up to 18V at 3.
0V input and 30V at 5.
0V input.
The 1 MHz switching frequency allows it to work with tiny external components, therefore minimize the footprint and cost in space consideration products.
One of the major applications for ...
