    LM53635MQRNLRQ1 Typical application Circuitry


    The LM53635MQRNLRQ1, developed by Texas Instruments, is a robust, automotive-qualified buck regulator that can manage voltages ranging from 3.5V to 36V, with a rated output current of 3.5A. For precision in your LM53635MQRNLRQ1 chip circuit connection, here is an instructional guide addressing each pin:

    1. Power Input and Output Pins:The VIN (pin 10) supplies the power to the LM53635MQRNLRQ1. Connect this pin to a power source in line with the chip's specifications. The SW (pin 6) is the switch node that connects to the inductor. The PGND (pin 7) is the power ground.

    2. Feedback and Compensation:The feedback (FB, pin 3) pin is where the feedback voltage is input, typically through a voltage-divider from the output voltage. The COMP (pin 4) is the compensation pin used for frequency compensation. Usually, a series RC network is connected to this pin for stability.

    3. Enable and Power Good: The device is enabled or disabled using the EN (pin 1) pin. When driven high, the device is enabled; when driven low, it is in shutdown mode. The GOOD (pin 2) is an open-drain output and goes high when the output voltage is within the power good threshold.

    4. Synchronization and Mode Selection:The SYNC/MODE (pin 5) pin allows for synchronization to an external clock and mode selection. Connect this pin to an external clock for synchronization, or ground for forced-PWM mode, or leave it open for auto-PWM/PFM mode.

    5. Thermal Pad:The thermal pad (on the bottom of the package) is the heat sink for the LM53635MQRNLRQ1. It must be electrically connected to AND and should be soldered to a large ground plane for efficient heat dissipation.

    6. Boot and AND Pins:The BOOT (pin 8) pin is the bootstrapped supply voltage for the high-side gate driver. A small ceramic capacitor is connected between this pin and SW. The AND (pin 9) is the analog ground for the device and should be connected to the system ground plane.

    7. Frequency Setting Pin: The device's switching frequency is set by the RT (pin 11) pin. Connect a resistor from this pin to ground to set the frequency.

    Remember, each application is unique, so always refer to the LM53635MQRNLRQ1 data sheet from Texas Instruments for complete instructions and considerations concerning your specific design requirements.
