LM25141QRGERQ1 is a synchronous step-down converter, which is suitable for high voltage and wide input voltage step-down regulator applications. The control method is peak current mode control. Current mode control can provide internal line feedforward, period-by-cycle current limitation and simplified loop compensation. LM25141-Q1 has the control function of yaw rate, which can easily meet the requirements of CISPR and automobile EMI.

LM25141QRGERQ1 has two switching frequencies: 2.2MHz and 440kHz. The grid driver has the control function of the swing rate, which can be adjusted to reduce EMI.

LM25141QRGERQ1 improves low power efficiency by running in skip cycle mode under light load or no load conditions. LM25141-Q1 has a high voltage bias regulator that can automatically switch to the external bias power supply, which can reduce the IQ current from VIN. Other functions include frequency synchronization, cycle by cycle current limit, intermittent mode fault protection under continuous overload and normal power output.
