Additional Details

The MAX42408/MAX42410 are highly-integrated synchronous buck converters with internal high-side and low-side switches. The ICs deliver up to 8A/10A with input voltage from 4.5V to 36V. The voltage quality can be monitored by the PGOOD signal. The MAX42408/MAX42410 can operate in the dropout mode by running at very high duty cycle, which make them ideal for industrial applications.

The MAX42408/MAX42410 offer programmable output-voltage options. High switching frequency at 1.5MHz and 400kHz options allow for small external components and reduced output ripple. SYNC input programmability enables three modes for optimized performance: forced PWM mode, skip mode with ultra-low quiescent current, and synchronization to an external clock.

The MAX42408/MAX42410 also come with dual-phase capability, which allows up to 20A designs. Two ICs can be configured as a controller and target with dynamic current sharing and 180º out-of-phase operation.

The MAX42408/MAX42410 are available in a small 3.5mm x 3.75mm, 17-pin FC2QFN package. They are pin-to-pin compatible with the MAX42405/MAX42406 (5A to 6A) family of products.
