MAX16903
2.1MHz, High-Voltage, 1A Mini-Buck Converter
General Description
The MAX16903 is a small, synchronous buck converter
with integrated high-side and low-side switches. The
device is designed to deliver 1A 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 MAX16903 can oper-
ate in dropout by running at 97% duty cycle, making it
ideal for automotive and industrial applications.
The MAX16903 operates at a 2.1MHz frequency, allow-
ing 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
MAX16903 can be ordered with spread-spectrum fre-
quency modulation, designed to minimize EMI-radiated
emissions due to the modulation frequency.
The MAX16903 is available in a thermally enhanced,
3mm x 3mm, 10-pin TDFN package or a 16-pin TSSOP
package. The MAX16903 operates over the -40°C to
+125°C automotive temperature range.
