    LMZ35003RKGR Typical application Circuitry


    The LMZ35003RKGR is a step-down DC-DC converter from Texas Instruments that provides power-supply solutions for products using a 12V or 24V rail. The LMZ35003RKGR offers high efficiency and small form factor solution due to its integrated inductor. 

    Let's dive into the key aspects of a typical application circuit for the LMZ35003RKGR:

    1. Input and Output Capacitors: These capacitors provide stability for the DC-DC converter. Between the VIN and GND pins, a ceramic capacitor with a value of around 10 F should be attached. For the output, a larger capacitor of 47µF or more should be used to reduce output voltage ripple.

    2.Bootstrap Capacitor: Join a 0.1-F ceramic capacitor to the BOOT and SW pins. This capacitor aids in powering the internal high-side NMOS switch.

    3. Soft-Start Capacitor: The SS/TRK pin is used for setting the soft-start time. A capacitor between this pin and the ground determines the rate at which the output voltage rises during startup.

    4. Feedback Resistors: The LMZ35003RKGR has an adjustable output voltage, and a voltage divider from the output to the FB pin sets the output voltage. Usually, the lower resistor is 10 km, while the upper resistance is determined by the required output voltage.

    5. Frequency Selection: The RT/SYNC pin allows for adjusting the switching frequency. A resistor linked from this pin to the ground regulates the frequency. An alternative method for synchronization is to apply an external clock signal to this pin.

    6. Enable and Power Good: The EN and PG pins are used for enabling the converter and monitoring the status of the output voltage respectively. The PG pin can be connected to the enable pin of a downstream device to ensure correct power sequencing.

    7. Thermal Management: The Powered package of the LMZ35003RKGR should be soldered to the PCB, and thermal via should be placed under the IC to aid in heat dissipation.

    Remember, the above points are just a guide, and the design of your specific application may require modifications based on its unique requirements. Always ensure to refer to the datasheet and reference design documents when designing your circuit.
