OZ9993
FEATURES
• High frequency DC/DC boost converter controller
• Supports a single cell Li-Ion battery
• Fixed 975kHz switching frequency
• Integrated power MOSFET with over-current protection
• Output over-voltage protection
• Open diode or output short circuit protection
• Thermal protection
GENERAL DESCRIPTION
OZ9993 is a high efficiency, DC/DC controller with an integrated power MOS-
FET that drives one string of LEDs. It provides the user with a low cost solution
that requires minimum components for the boost regulator and is suitable for
applications requiring a single cell Li-Ion battery.
A soft start feature is provided to minimize in-rush current during start-up.
APPLICATIONS
• Netbook Computer
• PND
• Camcorder
