AOZ1375DI is a power management integrated circuit (PMIC) component developed by Alpha & Omega Semiconductor (AOS) specifically for load and power distribution applications. AOZ1375DI is a single stage synchronous rectifier with integrated N-Channel MOSFETs, P-Channel MOSFETs, and adjustable current sensing. It provides 5V level shifting with synchronous rectification operation, effectively increasing efficiency. The AOZ1375DI is suitable for use in applications where voltage conversion is required, such as DC/DC converters, LEDs, power distribution switches, and load drivers.

Working Principle

The AOZ1375DI operates in buck mode and is designed for a single stage buck converter. The input voltage (VIN) supplied to the AOZ1375DI is converted to an output voltage (VOUT) based on the duty cycle, ripple current (ΔIOUT) and switching frequency (fsw). The AOZ1375DI utilizes a synchronous rectification technique with N-Channel MOSFETs that can reduce switching losses from the power switch. The N-Channel MOSFET acts as the main switch, while the P-Channel MOSFETs are used to discharge the output capacitors when the switching stops.

The peak current level of the N-Channel MOSFET is measured with a current sensing circuit and can be programmed through the IREF pin. The current sensing level is used to limit the maximum current of the N-Channel MOSFET and to reduce power loss. The AOZ1375DI offers a level shifting feature with 5V gate input, which is useful for applications that require a high voltage level shift.
