Bi-CMOS IC
LV5050NV DC / DC Converter Controller
Overview
The LV5050NV is a high efficiency DC/DC converter controller 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 1-channel
• Input UVLO circuit,
• Built-in over current detection function
• Built-in soft-start/soft-stop function
• Built-in start-up delay circuit
• Built-in output voltage monitor function (Under voltage protection with power good and timer latch)
• Synchronized operation is possible between different devices.
