Introduction

AI Translation

LM25141-Q1 is a synchronous buck converter designed for high-voltage wide input voltage step-down regulator applications. The control method is peak current mode control, which provides internal line feedforward, cycle-by-cycle current limiting, and simplified loop compensation. LM25141-Q1 features slew rate control to easily meet CISPR and automotive EMI requirements. LM25141-Q1 offers two selectable switching frequencies: 2.2MHz and 440kHz. The gate driver features slew rate control that can be adjusted to reduce EMI. Under light-load or no-load conditions, LM25141-Q1 improves low-power efficiency by operating in pulse-skipping mode. LM25141-Q1 incorporates a high-voltage bias regulator that automatically switches to an external bias supply, reducing IQ current from VIN. Additional features include frequency synchronization, cycle-by-cycle current limiting, hiccup-mode fault protection under sustained overload conditions, and a power-good output.
