Introduction

AI Translation

LM5141-Q1 is a synchronous buck controller for high-voltage wide VIN step-down converter applications. The control method is based on peak current mode control, which offers inherent line feedforward, cycle-by-cycle current limiting, and simplified loop compensation. The LM5141-Q1 features slew rate control on the gate drivers, enabling easy compliance with CISPR and automotive EMI requirements. The LM5141-Q1 is available in two switching frequency options: 2.2MHz and 440kHz. The gate drivers feature slew rate control that can be adjusted to reduce EMI. Under light-load or no-load conditions, the LM5141-Q1 improves light-load efficiency by operating in skip-cycle mode. The LM5141-Q1 includes a high-voltage bias regulator that automatically switches to an external bias supply, improving efficiency and reducing I0 (from VIN). Adjustable features include frequency synchronization, cycle-by-cycle current limiting, hiccup mode fault protection for sustained overload conditions, and power good output.
