LV5052V
Bi-CMOS IC
DC/DC Converter Controller
http://onsemi.com
Built-in 2-channels
Overview
The LV5052V 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)
