MP1493
3A, 4.2V-16V Input, Fast Transient
Synchronous Step-down Converter
The Future of Analog IC Technology
DESCRIPTION
The MP1493 is a fully integrated, high–
efficiency 3A synchronous rectified step-down
converter. The MP1493 operates at high
efficiency over a wide output current load range.
Adaptive Constant-On-Time (COT) control
mode provides fast transient response, eases
loop stabilization, and operates with a low-cost
electrolytic capacitor.
The MP1493 requires a minimum number of
readily available standard external components
and is available in an 8-pin SOIC ROHS
compliant package.
