Application Field and Working Principle:

AOZ6643DI is a DC-DC switching regulator designed for use in power management solutions. The device provides two parallel channels, which enables two separate power supplies to a single load. The device offers excellent power efficiency and low power consumption and is suitable for a variety of applications.

The AOZ6643DI features a Constant Frequency Voltage Mode (CFVM) control with integrated oscillator and fast-transient response. The device is capable of achieving high output power even at low input voltages. The output voltage can be set by external resistors. The device also has an adjustable soft-start feature, which limits inrush current and prevents overshoot during output voltage transients.

The device also features over-voltage protection and under-voltage protection. In the case of an over-voltage condition, the device will reduce the output voltage to a safe level and enable the over-voltage protection circuit. The under-voltage protection circuit will enable a reduction in the output voltage when it falls below a certain threshold.

The AOZ6643DI is designed for reliability and the use of advanced packaging materials. It has built-in ESD protection and is qualified for automotive grade application.

In summary, AOZ6643DI is a dual-channel DC-DC switching regulator, suitable for advanced power management solutions. It provides excellent power efficiency, low power consumption and high thermal performance, as well as over-voltage and under-voltage protection. Its wide range of output voltage, up to 2A load current, integrated FETs, programmable soft-start and adjustable output voltage make it suitable for a variety of applications.
