BU90023NUX
Step-down Switching regulators with Built-in Power MOSFET

The BU9002xNUX are a high efficiency 1MHz synchronous step-down switching regulator with low current PFM mode.
It provides up to 1.5A load current and an input voltage range from 4.5V to 5.5V, optimized for various applications with input voltage range up to 5V.
BU9002xNUX has a mode control pin that allows the user to select Forced PWM (Pulse Width Modulation) mode or PFM (Pulse Frequency Modulation) and PWM auto change mode utilized power save operation at light load current.
