AOZ3046PI is a DC-DC switching regulator from Power Integrations, Inc. It is a 2-channel regulator for point-of-load regulation. It has a wide input range from 4.5V up to 28V, and a programmable output voltage from 0.8V to 17V. The output current across both channels can be up to 1.2A (2.4A combined).

Application Fields of AOZ3046PI

AOZ3046PI is mainly used in applications where high precision voltage regulation is required. It provides excellent spike immunity and low output voltage ripple which make it well-suited for applications such as microcontrollers, FPGAs, ASSPs and other digital systems, as well as telecommunications, medical and industrial equipment.

Working Principle of AOZ3046PI

AOZ3046PI utilizes a synchronous rectification topology which enhances efficiency and reduces component count. It uses two FETs for switching power on and off. The FETs are driven by the integrated pulse-width modulation (PWM) controller. When the input voltage decreases, the PWM controller increases the duty cycle of the FETs, allowing a higher current to flow into the output. This increases the output voltage, compensating for the drop in input voltage.

Additionally, AOZ3046PI can be programmed to operate in CV/CC mode or discrete output voltages by using an external resistor. It also features soft-start and hiccup-mode over-current protection. It has an excellent thermal performance with a wide variety of package options. All these features make it well suited for modern high-load applications.
