For LCD/OLED/CCD

Step-up

These products are suitable for the power management of LCD, OLED and CCD. Many variations are available such as step-up DC/DC controller, step-up 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.
