Application field

AN33017UA-VB is ideal for automotive applications due to its high efficiency and wide temperature range. This product can also be used in consumer and communication devices such as smartphones, GPS navigations, tablets or any other product which requires a dc-dc switching regulator. This product provides high system safety margin and its small size make it perfect for today’s smaller electronic products. In addition, it can also be used in industrial applications such as robotic systems and other control systems which require higher output voltage and current.

Working principle

AN33017UA-VB is a monolithic DC DC switching regulator designed to operate in step-down, step-up and step-up/down configurations. It has an internal synchronous rectifier for increased efficient at high current and temperature. The output voltage of the device can be controlled by an external resistor or an internal PWM signal. When the output current is greater than the rated current of the device, the output voltage will droop and the output voltage can be controlled by an external resistor to maintain the desired output voltage.

The device has a built-in protection against over-voltage, over-current, over-temperature, and reverse voltage. The protection and fault status can be monitored on their associated pins. The device is internally compensated and requires no external components except the external sense resistor and current limit resistor. The device uses a fixed frequency switching scheme with a pulse frequency modulation (PFM) option, which provides adjustable duty cycle adjustment.

Conclusion

AN33017UA-VB DC DC switching regulator is a great solution for many application requirements. With its high efficiency, wide temperature range and small size, it offers the perfect solution for automotive, industrial and consumer applications. The device is easy to use, with no external components required
