Overview of the AS1323-BTTT-27

The AS1323-BTTT-27 is a buck converter from ams AG with integrated switch current limit, gate driver and undervoltage lockout. It provides a 4.5V to 36V input voltage range and an output voltage range of 0.83V to 28V. The device can provide up to 1A load current and it has an adjustable switching frequency range of 400kHz to 3MHz. The device comes in a 4-pin DFN package and is designed for a wide range of applications including industrial, consumer and automotive.

Application Field of the AS1323-BTTT-27

The AS1323-BTTT-27 is a versatile device suited for a wide range of applications thanks to its wide input voltage range, high efficiency and low quiescent current. The device can be used in industrial applications such as programmable logic controllers and actuators, as well as consumer applications like LED lighting, medical devices, multimedia devices and PC peripherals. The device is also suitable for automotive applications such as displays, interior lighting and audio systems.

Working Principle of the AS1323-BTTT-27

The working principle of the AS1323-BTTT-27 can be broken down into three basic stages: power-on sequence, conversion and switching. In the power-on sequence, the device detects the input voltage and sets the undervoltage lockout (UVLO) threshold voltage. The UVLO threshold voltage prevents the device from operating at low voltages, ensuring circuit protection. The device then checks the output voltage and operates in either step-up or step-down mode as necessary. The conversion process then begins, where the device modulates the duty cycle of the switch to convert the input voltage to the desired output voltage.

Finally, in the switching process, the gate driver blocks and unblocks the switch depending on the duty cycle determined in the conversion process and so the output voltage is regulated and maintained. Apart from the switching frequency which can be adjusted, the device also features a programmable current limit, soft start and low-noise operation, making it highly efficient and suitable for noise-sensitive applications.

Conclusion

In summary, the AS1323-BTTT-27 is a DC DC switching regulator belonging to the Voltage Regulators range of Power Management Integration Circuits (PMICs). It is a highly efficient and versatile device suited for a wide range of applications thanks to its wide input voltage range, high efficiency and low quiescent current. It features a programmable current limit, soft start and low-noise operation, making it highly suitable for noise-sensitive applications. Hopefully this article has been a useful introduction to the application field and working principle of the AS1323-BTTT-27.
