NX2820
2A SOURCE/SINK LDO & SYNCHRONOUS SWITCHING
CONTROLLER
DESCRIPTION
The NX2820 is a combination of synchronous Buck con- n
troller IC and 2A internal source/sink LDO regulator. It is n
designed for DDR memory application where typically n
synchronous controller provides either a 2.5V Vddq for n
DDR1 type memory(1.8V for DDRII) and the internal LDO n
supplies Vtt from the Vddq supply.
n
NX2820 features internal digital soft start,VCC n
undervoltage lock out, bus enable as well as over current limit by sensing low side MOSFET Rdson. The n
source and sink LDO is protected by thermal shutdown
and current limit.
