AOZ1043PI is a high performance DC-DC switch regulator. It is designed to produce a regulated output voltage from a variable input voltage. The device features a wide input voltage range, low quiescent current, fast transient response, and excellent efficiency at low input and output voltages. The device is suitable for a variety of power conversion applications, from consumer, industrial, automotive, and military and space.
AOZ1043PI consists of a fixed frequency, current-mode controller and security functions, optimized to handle a wide range of output load dynamics. The device operates in pulse width modulated (PWM) mode when the input supply is low and in pulse frequency modulated (PFM) mode when the input supply is high. In PFM mode, the device eliminates the need for a separate external shutdown switch by internally-selectable hysteretic operation.
The AOZ1043PI has a wide 3.3V-30V input voltage range and can deliver outputs of up to 5A (with adequate external pass transistor). The device supports input voltages up to 64V (with an external FFM-mode shutdown switch) for automotive grade operation. The optimized power conversion architecture minimizes the size of the external components, reducing the PCB footprint and cost.
The internal soft-start circuit of the AOZ1043PI allows a gradual current ramp-up to prevent overshoot at the output as well as inrush current from the input supply. Other safety features include a clock over-temperature shortcut and undervoltage lockout. The device can also be monitored for temperature and overcurrent status, output voltage accuracy and soft-start characteristics, via an integrated diagnostic pin.
The AOZ1043PI is an ideal power conversion solution for consumer, industrial and automative applications. It is suitable for a wide range of power applications, such as LED lighting, portable device chargers, DC motors, PLC’s, telecom/battery-supported industrial control systems and notebooks.
In summary, AOZ1043PI is a high-performance DC-DC switch regulator which can produce regulated output voltage from a variable input voltage. It features a wide input voltage range, low quiescent current, fast transient response and excellent efficiency at low input and output voltages. The device is suitable for a variety of power conversion applications including consumer, industrial, automotive and military and space. It is an ideal power solution for consumer, industrial, and automotive applications.
