Power Management ICs (DC/DC Converter)
DC/DC Converters Lineup for LCD / OLED / CCD
New :
Thermal : Thermal shutdown circuit Discharge : Auto-Discharge function Sequence : Power on sequence controllable
These products are suitable for the power management of LCD, OLED and CCD. Many variations are available such as step-up DC/DC controller, stepup
and step-down dual output converter and step-up and positive / negative charge pump triple output converter. These products include an under-voltage
lockout circuit (UVLO), and a latch type protection circuit. The products with a built-in the sequence control circuit
option are able to control a start-up sequence and a shutdown sequence.
The products highlighted in light blue rows are major products that are shown in the "DC/DC Converters Lineup in order of Input Voltage and Function".
