Voltage controller for CD-ROM
BH6552FV
BH6552FV is a voltage controller developed for CD-ROM. This IC incorporates 3.3V output DC/DC converter and reset circuit into a single chip.
Features < 3.3V DC / DC converter > Intended for low drain current by adopting sync rectification type. Power MOS Tr is contained. 3.3V DC/DC converter reduces variation through laser trimming (3.3V 2%). Built-in mute function. < Reset circuit > Source voltage Reset reduces variation through laser trimming (3.7V 2%).
