AOZ1615DI is a DC-DC switching regulator from the PMIC (Power Management Integrated Circuit) family. It is used to accurately regulate and maintain a specified voltage output when the input voltage sourcing varies or for applications requiring a precise reference voltage or output voltage preset. It also provides a constant-current output for steady state as well as transient conditions.

The AOZ1615DI is a high-efficiency step-down, synchronous-rectified DC to DC converter. It converts an unregulated input voltage in the range of 8V to 90V and provides a single output voltage which can be adjustable from 0.6V to 95% of the input voltage. It features an integrated 1-bit MODE pin that can be used to select between PWM and Pulse-Frequency-Modulation (PFM) operation. This switching regulator offers low-noise operation and high switching frequency. It also features 85 percent efficiency with a maximum rated output current of 2.4A.

AOZ1615DI has a wide range of applications including laptops, telecommunication equipment, automotive systems, FPGA power supplies and industrial power supplies. In laptops, it can be used to supply power to CPUs, GPUs and other power-hungry components. In automotive systems, it can be used to provide power to LED lights, entertainment systems and other systems needing higher voltage and current output. In FPGA power supplies, it is particularly well suited for providing power to multilayered FPGAs.

The AOZ1615DI operates with synchronous rectification and integrated conversion topology which allows it to achieve high efficiency with fast transient response, providing wide output power range. It features excellent line and load regulation, high power efficiency, low EMI and low extraneous noise.

The AOZ1615DI utilizes two PNP transistors as the main power switch in order to drive an inductor/ Schottky diode power supply stage. It features a maximum duty cycle of 35 percent at 1MHz and reaches 95 percent efficiency at 200KHz. It offers short loop-compensation design with minimum components. The voltage feedback loop consists of a voltage divider, an error amplifier and a phase compensation capacitor.

The AOZ1615DI also includes a wide range of protectors such as over-current protection, over temperature protection and UVLO. The over-current protection is activated when the output current exceeds the preset threshold. It is used to protect the MOSFET from overheating and damage. The over temperature protection is used to protect the device from thermal overload. The UVLO (Under Voltage Lockout) feature is used to prevent the device from operating when the input voltage is too low.

The AOZ1615DI switching regulator is the perfect choice for a wide variety of applications with its many features and wide operating temperature range of -40°C to +105°C. It offers high efficiency and high power density with fast transient response, low EMI and low extraneous noise. It is ideal for applications requiring a wide input voltage range, high efficiency and low component count.
