Qualified for Automotive Applications  
Automotive Applications Including:  
AEC-Q100 Qualified With the Following Results:  
Infotainment Systems  
Device Temperature Grade 1: –40°C to  
+125°C Ambient Operating Temperature  
Instrumentation Clusters  
Advanced Driver Assistance Systems (ADAS)  
Device HBM ESD Classification Level 2  
Device CDM ESD Classification Level C4B  
3 Description  
The LM5141-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  
LM5141-Q1 features slew rate control to simplify the  
compliance with CISPR and automotive EMI  
requirements.  
VIN: 3.8 V to 65 V (70 V Absolute Maximum)  
Output: Fixed 3.3 V, 5 V, or Adjustable From  
1.5 V to 15 V with ±0.8% Accuracy  
Fixed 2.2-MHz or 440-kHz Switching Frequency  
with ±5% Accuracy  
High-Side and Low-Side Gate Drive With Slew-  
Rate Control  
Optional Frequency Shift by Varying an Analog  
Voltage or RT Resistor  
The LM5141-Q1 has two selectable switching  
frequencies: 2.2 MHz and 440 kHz. Gate drivers with  
slew rate Control that can be adjusted to reduce EMI.  
Optional Synchronization to an External Clock  
Optional Spread Spectrum  
In light or no-load conditions, the LM5141-Q1  
operates in skip cycle mode for improved low power  
efficiency. The LM5141-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.  
Shutdown Mode IQ: 10 µA Typical  
Low Standby Mode IQ: 35 µA Typical
