The MAX26408E/MAX26410E are highly-integrated synchronous buck converters with internal high-side and low-side switches. The ICs deliver up to 8A/10A with input voltages from 3.0V to 36V. The voltage quality can be monitored by the PGOOD signal. The MAX26408E/MAX26410E can operate in dropout mode by running at 99% duty cycle, making them ideal for industrial applications.
The MAX26408E/MAX26410E offer programmable or fixed output voltage options. High switching frequency at 2.1MHz and 400kHz options allows for small external components reduced output ripple, and guarantees no AM interference. SYNC input programmability enables three modes for optimized performance: forced-PWM (FPWM) mode, skip mode with ultra-low quiescent current, and synchronization to an external clock. The spread-spectrum option minimizes EMI radiated emissions. It also features reduced output capacitor requirement, windowed PGOOD, improved output voltage accuracy, and EN threshold accuracy.
The MAX26408E/MAX26410E also come with dual-phase capability, allowing up to 20A designs. Two ICs can be configured as a controller and target with dynamic current sharing and 180° out-of-phase operation.
The MAX26408E/MAX26410E are available in small 3.5mm x 3.75mm, 17-pin FC2QFN packages. The FC2QFN package is pin-to-pin compatible with the MAX26404/MAX26405/MAX26406 (4A to 6A) family of products.
