LM53601LQDSXTQ1 Descrizione generale

The LM53600-Q1 and LM53601-Q1 synchronous buck regulator devices are engineered with automotive applications in mind, providing a versatile and efficient solution for power supply requirements. These regulators offer the flexibility of 5 V, 3.3 V, or adjustable output voltages, catering to a wide range of power needs in automotive systems. With a maximum load current support of up to 650 mA for the LM53600-Q1 and 1000 mA for the LM53601-Q1, these devices are capable of delivering reliable power delivery in demanding automotive environments. The advanced high-speed circuitry allows for precise regulation from an input voltage of 18 V to an output of 3.3 V at a fixed frequency of 2.1 MHz, ensuring stable performance across various load conditions. Additionally, the innovative architecture of these regulators enables the generation of a 3.3-V output from an input voltage as low as 3.8 V, enhancing their versatility and suitability for different power supply scenarios
