GENERAL DESCRIPTION
The MAX20408/MAX20410/MAX20408E/MAX20410E can operate in dropout mode by running at 99% duty cycle, making them ideal for automotive and industrial applications. The MAX20408/MAX20410/MAX20408E/MAX20410E offer programmable or fixed output voltage options. High switching frequency at 2.1MHz and 400kHz options allow for small external components, reduced output ripple, and guarantee 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. The MAX20408E/MAX20410E feature reduced output capacitor requirement, windowed PGOOD, improved output voltage accuracy, and EN threshold accuracy. The MAX20408/MAX20410/MAX20408E/MAX20410E 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-ofphase operation.
