Bi-CMOS IC
Built-in 2-channels
DC/DC Converter Controller
Overview
The LV5065VB is a high efficiency DC/DC converter controller with 2-channels IC adopting a synchronous rectifying
system. Incorporating numerous functions on a single chip with easy external setting, it can be used for a wide variety of
applications. This device is optimal for use in internal power supply systems which are used in electronic devices,
LCD-TVs, DVD recorders, etc.
Functions
• Step-down DC/DC converter controller with 2-channel
• Built-in input UVLO circuit, Over current detection function, soft-start/soft-stop function and Start-up delay circuit
• Built-in output voltage monitor function (Under voltage protection with power good and timer latch)
• 180 degree interleaving operation during 1-phase to 2-phase
• Synchronized operation is possible (Master-slave operation is possible when using plural devices)
