AOZ1269QI-02

AOZ1269QI-02 Application Field and Working PrincipleThe AOZ1269QI-02 is a single transistor step-down power supply. It is a DC-DC switching regulator which can provide a maximum of 2A output current. The device has high efficiency, low ripple and low noise.The AOZ1269QI-02 is specially designed for use in low voltage, space-constrained applications such as mobile phones, tablets, notebook computers, and remote control toys. It is also suitable for automotive applications such as on-board chargers, dash mount displays, and starter power selection systems.The AOZ1269QI-02 is capable of delivering an output voltage in the range of 0.8V to 5V, depending on the input voltage. The regulator also has a built-in current-limit protection which prevents excessive current and gives the circuit a more stable performance.The AOZ1269QI-02 has a high efficiency of up to 95%, further improving power delivery and reducing power losses. The device comes with thermal protection, allowing it to be used in a wide variety of applications.The working principle of the AOZ1269QI-02 is based on the buck-boost topology. This topology works by switching the input voltage, allowing it to generate an output voltage that is either equal to, or lower than, the input voltage. When the input voltage is higher than the output voltage, the transistor will switch off and the transformer will provide the power to the output stage. When the input voltage is lower than the output voltage, the transistor will switch on, allowing the output voltage to be higher than the input voltage.The AOZ1269QI-02 can provide a wide variety of additional features. It can be used in PWM control mode for precise adjustments, and also includes a soft-start/stop circuitry for quick response. It also comes with an integrated power switch, allowing it to be used without external switching elements.The AOZ1269QI-02 is a highly efficient and reliable device, designed to provide an ideal solution for a wide range of low voltage applications. With advanced features such as adaptive on-time control, high efficiency and low ripple, the AOZ1269QI-02 is an excellent choice for any application.
