LM53601MQDSXRQ1 Product Features
Automotive-Grade High Reliability: The LM53601MQDSXRQ1 is AEC-Q100 Grade 1 certified, ensuring stable operation in extreme ambient temperatures from -40°C to +150°C to meet the stringent requirements of automotive applications.
Wide Input Voltage Range: With a wide input range of 3.5V to 36V, the M01DSXRQ1 can easily cope with voltage fluctuations (e.g., cold start, sudden load drop) in automotive battery systems, and the 42V transient tolerance provides additional protection.
High integration and small size: Integrated power MOSFETs and compensation network in an advanced 4mm x 4mm HotRod™ QFN package dramatically saves valuable PCB space and simplifies design. Choosing the LM53601MQDSXRQ1 helps achieve a smaller design.
High Efficiency: The synchronous rectification architecture and optimised control scheme enable the LM53601MQDSXRQ1 to achieve up to 95% efficiency over a wide load range, reducing system temperature rise and power consumption.
High switching frequency of 2.1MHz: Allows the use of smaller inductors and output capacitors, further optimising solution size and cost, while helping to reduce the need for EMI filtering.
Comprehensive protection features: Built-in overcurrent protection (OCP), thermal shutdown (TSD), undervoltage lockout (UVLO), and power-good (PG) status outputs ensure that the LM53601MQDSXRQ1 and its loads are reliably protected from a wide range of abnormal conditions.
Low quiescent current: Optimised light-load efficiency for automotive modules that require constant power or low-power standby, the LM53601MQDSXRQ1 excels in these applications.
