The device is designed to deliver 600mA with input voltages from +3.
5V to +28V while using only 25μA quiescent current at no load.
Voltage quality can be monitored by observing the PGOOD signal.
The MAX16904 can operate in dropout by running at 97% duty cycle, making it ideal for automotive and industrial applications.
The MAX16904 operates at a 2.
1MHz frequency, allowing for small external components and reduced output ripple.
It guarantees no AM band interference.
SYNC input programmability enables three frequency modes for optimized performance: forced fixed-frequency operation, SKIP mode (ultra-low quiescent current of 25μA), and synchronization to an external clock.
The MAX16904 can be ordered with spread-spectrum frequency modulation, designed to minimize EMI-radiated emissions due to the modulation frequency.
The MAX16904 is available in a thermally enhanced, 3mm x 3mm, 10-pin TDFN package or a 16-pin TSSOP package.
The MAX16904 operates over the -40°C to +125°C automotive temperature range.
