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 an LDO mode for 100% duty cycle.
With a 2.5V to 5.5V 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. 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. The SP6669 is available in an adjustable output voltage version, using an external resistor divider circuit, as well as fixed output voltage versions of 1.2V, 1.5V and 1.8V.
Built-in over temperature and output overvoltage lock-out protections ensure safe operation under abnormal operating conditions.
