Description
General part information
MP2227 Series
The MP2227 is an internally compensated 1.3MHz fixed frequency PWM synchronous step-down regulator. MP2227 operates from a 3V to 24V input and generates an adjustable output voltage from 0.8V to 0.9xVIN at up to 3A load current. The MP2227 integrates a 160m? high-side switch and an 80m? synchronous rectifier for high efficiency without an external Schottky diode. With peak current mode control and internal compensation, it is stable with an output ceramic capacitor and a small inductor. Fault protection includes hiccup short-circuit protection, cycle-by-cycle current limiting and thermal shutdown. Other features include frequency synchronization and soft-start. The MP2227 is available in a small 3mm x 3mm 10-lead QFN package.3A Output Current Input Supply Range: 3V to 24V 160m? high-side, 80m? low-side Internal Power MOSFET Switches All Ceramic Output Capacitor Design Up to 95% Efficiency 1.3MHz Fixed Switching Frequency Adjustable Output from 0.8V to 0.9xVIN Internal LDO for VCC supply 1MHz to 2MHz Frequency Synchronization POK Thermal Shutdown Cycle-by-Cycle Current Limiting Hiccup Short Circuit Protection 10-lead, 3mm x 3mm QFN Package
