EV66P64A

EV66P64A is a MIC2133 evaluation board. The MIC2133 is an enhanced adaptive on-time, synchronous 2 phase buck controller featuring a proprietary Host/User control architecture. This advanced control architecture will enable optimal current sharing of phases in host and user modes with the option of cascading several user devices in parallel to increase current capability of the entire solution. The MIC2133 operates over an input supply range from 4.5V to 100V and can be used to supply up to 50A of output current for applications ranging from cloud computing to industrial and automotive. The output voltage is adjustable down to 0.6V with a guaranteed accuracy of ±0.5%. The device operates with programmable switching frequency from 200 KHz to 800 KHz. The application case of requiring higher current level (30A-50A) is limited to 12V input backplanes only.

• HyperLight load and phase shedding
• Automatic phase shedding of secondary phase, accurate current balancing between phases
• Accurate phasing between phases that are always 180° out of phase
• High voltage internal 5V LDO for single supply operation
• Secondary LDO to improve system efficiency
• Supports start up to pre-bias output, supports Adaptive Voltage Positioning (AVP) or droop
• Remote sense amplifier for tight output regulation
• Precision enable function for low stand-by current
• External programmable soft start, programmable current limit and hiccup short circuit protection
• Thermal shut down with hysteresis
