MAX42410 Description

The 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 MAX42410 can operate in the dropout mode by running at very high duty cycle, which make them ideal for industrial applications.

The 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 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 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.
