SD6251D6G-R

550MHz同步整流升壓IC;

The SD6251 is a high efficiency, fixed frequency 550KHz, current mode PWM boost DC/DC converter\nwhich could operate battery such as input voltage down to 2.5V? The converter output voltage can be\nadjusted to a maximum of 5.25V by an external resistor divider? Besides the converter includes a\n0.08Ω N-channel MOSFET switch and 0.12Ω P-channel synchronous rectifier? So no external\nSchottky diode is required and could get betterefficiency near 93% .\n\nFeatures \n? High Efficiency up to 93%\n? Low RDS(ON) Integrated Power MOSFET\n? NMOS 80mΩ / PMOS120mΩ\n? Wide Input Voltage Range: 2.5V to 5.5V\n? Fixed 550KHz Switching Frequency\n? Low-Power Mode for Light Load Conditions\n? ±2.0% Voltage Reference Accuracy\n? PMOS Current Limit for Short Circuit Protection\n? Low Quiescent Current\n? Output Ripple under 200mV? (Scope Full\nBandwidth)\n? Fast Transient Response\n? Built-In Soft Start Function\n? Over-Temperature Protection with Auto Recovery\n? Output Overvoltage Protection\n? Space-Saving SOT-23-6 Package \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
