JWQ5217 AEC-Q100 Qualified 5.5V/2A Sync. Step-Down Converter FEATURES DESCRIPTION  AEC-Q100 Qualified The JWQ5217 is a monolithic buck switching  2.5V to 5.5V Operating Input Range regulator based on COT architecture for fast  Up to 2A Output Current transient response. Operating with an input range  0.5V to VIN Adjustable Output Voltage of 2.5V~5.5V, JWQ5217 delivers 2A of continuous  Low Output Ripple over The Load Range output current with integrated P-Channel and N-  PFM Mode for High Efficiency at Light Load Channel MOSFETs. The internal synchronous  2MHz Switching Frequency power switches provide high efficiency without the  100% Duty Cycle for Lowest Dropout use of an external Schottky diode. At light loads,  Power Good Indicator the regulator operates in low frequency to  Output Discharge maintain high effic
