The Future of Analog IC Technology MP1601A 1A Synchronous Step-down Converter with Forced CCM Mode DESCRIPTION The MP1601A is a monolithic, step-down, switch-mode converter with built-in, internal power MOSFETs. It achieves 1A of continuous output current from a 2.3V to 5.5V input voltage range with excellent load and line regulation. The output voltage can be regulated as low as 0.6V. The constant-on-time (COT) control scheme in forced continuous conduction mode (CCM) provides a fast transient response, a low output voltage ripple, and eases loop stabilization. Fault protections include cycle-by-cycle current limiting and thermal shutdown. The MP1601A is available in an ultra-small SOT563 package and requires a minimal number of readily available, standard, external components.
