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.
