JWH5280 6V/3A Sync. Step-Down Converter Parameters Subject to Change Without Notice DESCRIPTION FEATURES The JWH5280 is a monolithic buck switching  2.5V to 6V Operating Input Range regulator based on COT architecture for fast  Up to 3A Output Current transient response. Operating with an input range  0.8V to VIN Adjustable Output Voltage of 2.5V~6V, JW H5280 delivers 3A of continuous  2MHz Switching Frequency output current with integrated P-Channel and  100% Duty Cycle for Lowest Dropout N-Channel MOSFETs. The internal synchronous  Power Good Indicator power switches provide high efficiency without  Output Discharge the use of an external Schottky diode. At light  Input Under Voltage Lockout loads, the regulator operates in low frequency to  Output Short Circuit Protection  Thermal Protection maintain high efficiency and low output ripples.  Available in QFN2X2-7 Package JWH5280 guarantees robustness with output short protection, thermal protection, current APPLICATIONS run-away protection, and input under voltage 制  Battery-Powered Application lockout.  POL Supply from Single or Multiple Li-Ion JWH5280
