2.1MHz, High-Voltage,

600mA Mini-Buck Converter

MAX16904

General Description

Features

The MAX16904 is a small, synchronous buck converter

with integrated high-side and low-side switches. 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 oper-

ate in dropout by running at 97% duty cycle, making it

ideal for automotive and industrial applications.

♦ Wide +3.5V to +28V Input Voltage Range

♦ Tolerates Input Voltage Transients to +42V

♦ 600mA Minimum Output Current with Overcurrent

Protection

♦ Fixed Output Voltages (+3.3V and +5V)

♦ 2.1MHz Switching Frequency with Three Modes of

Operation

The MAX16904 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

MAX16904 can be ordered with spread-spectrum fre-

quency modulation, designed to minimize EMI-radiated

emissions due to the modulation frequency.

Forced Fixed-Frequency Operation

External Frequency Synchronization

♦ Optional Spread-Spectrum Frequency Modulation

♦ Power-Good Output

♦ Enable-Pin Compatible from +3.3V Logic Level to

+42V

♦ Thermal Shutdown Protection

♦ -40°C to +125°C Automotive Temperature Range

♦ 10-Pin TDFN-EP or 16-Pin TSSOP-EP Packages

♦ AEC-Q100 Qualified

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.
