DESCRIPTION
The SS6612 is a high-efficiency step-up DC/DC converter, with a start-up voltage as low as 0.8V, and an operating voltage down to 0.7V. Consuming  only 20µA of quiescent current, this device includes a built-in synchronous rectifier that reduces size and cost by eliminating the need for an external Schottky diode, and improves  overall efficiency  by  minimizing losses.
The switching frequency  can  range  up  to 500KHz depending on the load and input volt age. The output voltage can be easily set; by two external resistors for1.8V to 5.5V; connecting FB to OUT to get 3.3V; or connecting to GND to get 5.0V. For additional design flexibility, the peak current of theinternal switch is selectable (0.65A or 1.0A). The SS6612 also features a circuit that eliminates noise caused by inductor ringing. 

FEATURES
