描述 Description
The RS53319 is a high-power density, fully
integrated synchronous buck converter. It has a
wide input voltage range, and can support up to 20A
continuous output current at defined conditions.
LDO is integrated internally, which is very suitable
for single input supply conditions. External bias is
optional for maximizing efficiency. A differential
sensing scheme and an internal feedback reference
voltage achieve ±1% tolerance over full temperature
range and, in conjunction, they perform an excellent
line and load regulation.
Switching frequency can be easily adjusted from
600kHz, 800kHz, 1000kHz, to 2.1MHz. The
RS53319 uses patented Robust Constant On-Time
(RCOTTM) control scheme with fast transient
response. Pure MLCC output capacitors can be
used to save space and cost.
RS53319 has full protection features including OCP,
NOCP, OVP, UVP and over temperature protection
(OTP).
The RS53319 is available in a 3mm x 4mm 21-Pin
QFN package.
