Analog Devices / Maxim Integrated MAX16909 Step-Down Converters
Analog Devices MAX16909 Step-Down Converters are 3A, current-mode, step-down converters with an integrated high-side switch. The device features an adjustable switching frequency (220kHz to 1MHz) and pin-selectable output voltage of 5V fixed or 1V to 10V adjustable. Also featured is a wide input voltage range of 3.5V to 36V and high-duty cycle operation during under-voltage transients. The MAX16909 Step-Down Converter from Analog Devices is ideally suited for automotive and industrial applications.
