3 Description
The LM25141-Q1 is a synchronous buck controller,
intended
for
high
voltage
wide
VIN step-down
converter applications. The control method is peak
current mode control. Current mode control provides
inherent line feed-forward, cycle-by-cycle current
limiting,
and
ease
of
loop
compensation.
The
LM25141-Q1 features slew rate control to simplify the
compliance
with
CISPR
and
Automotive
EMI
requirements.
The
LM25141-Q1
has
two
selectable
switching
frequencies: 2.2 MHz and 440 kHz. Gate Drivers with
Slew Rate Control can be adjusted to reduce EMI.
In light or no-load conditions, the LM25141-Q1
operates in skip cycle mode for improved low power
efficiency. The LM25141-Q1 has a high voltage bias
regulator with automatic switch-over to an external
bias to reduce the IQ current from VIN. Additional
features include frequency synchronization, cycle-by-
cycle current limit, hiccup mode fault protection for
sustained overload, and power good output.
