Texas Instruments Voltage Regulators - DC DC Switching Regulators LM63635DQDRRRQ1

The LM63635DQDRRRQ1 is a synchronous step-down DC/DC converter designed for automotive applications, capable of delivering up to 2.5 A of load current from an input voltage range of 3.5 V to 36 V. It is AEC-Q100 qualified, ensuring reliability in harsh automotive environments with an operating temperature range of -40¬8C to +150¬8C. The device features low quiescent current of 23 ¬µA, good EMI performance, and a minimum on time of 50 ns, making it suitable for various automotive systems including infotainment, body electronics, and advanced driver-assistance systems (ADAS). The LM63635DQDRRRQ1 offers design flexibility with pin-selectable output voltages of 3.3 V, 5 V, and adjustable outputs from 1 V to 20 V. It supports multiple switching frequencies (400 kHz, 2.1 MHz, and adjustable from 250 kHz to 2200 kHz) and operational modes (FPWM, auto, sync). The device is available in a compact WSON package, measuring 3.00 mm x 3.00 mm, which is advantageous for space-constrained applications. Protection features include thermal shutdown, input undervoltage lockout, and hiccup short-circuit protection, enhancing its robustness for automotive use.
