🔧 Application Guidelines
Design Considerations
The AAT3169 is designed for high efficiency and low noise. To achieve the best performance, it is recommended to use a 10uF input capacitor and a 10uF output capacitor. The device also features automatic shutdown and over-temperature protection for safe operation.
Installation Guidelines
The AAT3169 should be mounted on a PCB with adequate thermal dissipation. The device is sensitive to moisture, so it is recommended to follow standard reflow soldering procedures.
Operational Notes
The AAT3169 operates in a pulse-width modulation (PWM) mode. The device has a built-in soft-start to minimize inrush current during startup. The output voltage can be adjusted using an external resistor divider.
