    L6699DTR Typical application Circuitry


    A high-voltage resonant controller called the L6699DTR is made to give devices consistent power. It's particularly effective in appliances that demand high power. Let's go through a general explanation of how to connect a circuit using the L6699DTR.

    1. Initial Connections for the First L6699DTR:Start by connecting your power source to the VCC (Pin 16) and COM (Pin 8) pins of the L6699DTR. This will power the controller. Make sure to regulate the input voltage, as this controller operates at high voltages. Connect a capacitor between the VCC and COM pins to stabilize the power supply.

    2. Creating the Half-Bridge with the Second L6699DTR:The L6699DTR can be configured in a half-bridge topology, which is useful in power supply systems. Connect the HO (High-side gate driver output, Pin 11) and LO (Low-side gate driver output, Pin 10) pins to the gates of two power Moses. The VS pin (Pin 13) should be connected to the source of the high-side MOS FET.

    3. Implementing Pulse Width Modulation with the Third L6699DTR:Pulse Width Modulation (PWM) is a significant feature of the L6699DTR. The controller can generate a PWM signal on its own, through the CS pin (Pin 4), which senses the output current and helps in implementing PWM control.

    4. Protecting Your Circuit with the Fourth L6699DTR:The L6699DTR includes many built-in protection features. For example, the brownout protection can be implemented by connecting a resistor network to the VCC and BO (brownout, Pin 5) pins. For overcurrent protection, connect a sense resistor in series with the load and connect it to the CS pin (Pin 4).

    5. Incorporating Power Factor Correction with the Fifth L6699DTR:Finally, Power Factor Correction (PFC) is an important feature of power supply systems. You can achieve this with the L6699DTR by connecting the PFC controller output to the ZCD (Zero Current Detection, Pin 3) pin of the L6699DTR.This will ensure optimal power consumption by your device.

    Please be aware that this is a simplified explanation of how to connect a circuit with the L6699DTR. Always consult the specific data sheet for the L6699DTR and adhere to all safety guidelines when handling high-voltage components.
