The Future of Analog IC Technology DESCRIPTION The MP28115 is an internally compensated 1.5MHz fixed frequency PWM synchronous step-down regulator. MP28115 operates from a 2.7V to 6V input and generates an adjustable output voltage from 0.8V to 0.9xVIN at up to 4A load current. The MP28115 integrates a 60mΩ high-side switch and a 60mΩ synchronous rectifier for high efficiency without an external Schottky diode. With peak current mode control and internal compensation, the MP28115 based solution achieves minimum footprint and component count. Fault condition protection includes Hiccup short-circuit protection, cycleby-cycle current limiting and thermal shutdown. Other features include frequency synchronization input, internal soft-start and power good output.
