MOSFET
BU9002xNUX Series
●General Description 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.
●Features ■ Fast transient response ■ Automati...
