MaxLinear SP6669
The SP6669 is a synchronous current mode PWM step down (buck) converter capable of delivering up to 800mA of current. It features a pulse skip mode (PSM) for light load efficiency and a LDO mode for 100% duty cycle. With a 2.5V to 6.0V input voltage range and a 1.5MHz switching frequency, the SP6669 allows the use of small surface mount inductors and capacitors ideal for battery powered portable applications.| Part No. | SP6669 |

GENERAL DESCRIPTION
The internal synchronous switch increases efficiency and eliminates the need for an external Schottky diode. Low output voltages are easily supported with the 0.6V feedback reference voltage. Built-in over temperature and output over voltage lock-out protections insure safe operations under abnormal operating conditions. The SP6669 is offered in a RoHS compliant, “green”/halogen free 5-pin SOT23 package. TYPICAL APPLICATION DIAGRAM Rev. 5.0.0APPLICATIONS
