* 900 KHz current-mode PWM converter Built-in internal switch Adjustable output voltage up to 30V 2.7V to 16V in.

for YB1517 is in the dc to dc converter and OLED power supply and TFT panel power supply. When using YB1517 for white LE.

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 co.
