General Description

The MAX20004/MAX20006/MAX20008 are small, synchro-

nous, automotive buck converter devices with integrated

high-side and low-side MOSFETs. The device family can

deliver up to 8A with input voltages from 3.5V to 36V, while

using only 25μA quiescent current at no load. Voltage qual-

ity can be monitored by observing the RESET signal. The

devices can operate in dropout by running at 98% duty

cycle, making them ideal for automotive applications.

The devices offer fixed output voltages of 5V and 3.3V,

along with the ability to program the output voltage between

1V and 10V. Frequency is resistor programmable from

220kHz to 2.2MHz. The devices offer a forced fixed-fre-

quency PWM mode (FPWM) and skip mode with ultra-low

quiescent current. The devices can be factory programmed

to enable spread-spectrum switching to reduce EMI.

The MAX20004/MAX20006/MAX20008 are available in a

small, 3.5mm x 3.75mm, 17-pin FC2QFN package and use

very few external components.
