EV71S00A

EV71S00A is a MIC21LV32 evaluation board for a constant on-time, dual-phase synchronous buck controller with stackable multiphase capability up to eight phases. The MIC21LV32 operates over an input supply range from 4.5V to 36V and can be used to supply up to 50A of output current/phase. The output voltage is adjustable down to 0.6V with an ensured accuracy of ±1%. The device operates with programmable switching frequency from 100kHz to 1MHz per phase.

• 4.5V to 36V input supply range
• Output adjustable down to 0.6V and adaptive constant on time control
• High delta V operation
• Up to 50A output current per phase
• Any Capacitor™ stable
• Operates in CCM, stackable for multiphase operation up to eight phases
• Automatic phase shedding with settable thresholds
• High-voltage internal 5V LDO, secondary LDO to improve system efficiency
• External programmable soft start, supports start up to pre-bias O/P, remote sense amplifier
• Programmable current limit and hiccup protection, precision enable function for low stand-by current
