描述 Description

The RS53417 is a high-power density, fully

integrated synchronous buck converter. It has a

wide input voltage range and can support up to 6A

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 selected from

300kHz, 500kHz, 800kHz and 1100kHz. The

RS53417 uses Constant-On-Time control scheme

with fast transient response. Pure MLCC output

capacitors can be used to save space and cost.

RS53417 has full protection features. OCP, UVP,

UVLO and OTP are non-latch mode. OVP is latchoff

mode.

The RS53417 is available in a 2mm x 3mm 14-Pin

QFN package.
