Power Management ICs (DC/DC Converter) New : Under Development : Step-up DC/DC Converters Lineup (For white LED / For PMOLED and General use) These products are PWM step-up DC/DC converters, which are optimized to drive a white LEDs for background illumination or passive matrix OLED display with constant current. These products include an under-voltage lockout circuit (UVLO), and a soft-start circuit. These are also able to be used in a general step-up power supply. The products highlighted in yellow rows are major products that are shown in the "DC/DC Converters Lineup in order of Input Voltage and Function". Succeeding products are available for products highlighted in grey rows. We recommend the products shown in "Product Name".
