DESCRIPTION
The SS6620/21/22 are high-efficiency stepup DC/DC converters, with start-up voltage as low as 0.8V and operating with an input voltage down to 0.7V. Consuming only 20mA of quiescent current, these devices offer a built-in synchronous rectifier that reduces size and cost by eliminating the need for an external Schottky diode, improving overall efficiency by minimizing losses.

FEATURES
 • High efficiency of 93% (VIN=2.4V, VOUT=3.3V, IOUT=200mA).
 • Quiescent supply current of 20mA.
 • Power-saving shutdown mode (0.1mA typical).
 • Internal synchronous rectifier (no external diode )
 • Selectable current limit for reduced ripple (SS6622).
 • Low noise, anti-ringing feature (SS6622)
 • On-chip low-battery detector.
 • Low-battery hysteresis

APPLICATIONS
 • Palmtop & notebook computers.
 • PDAs
 • Wireless phones
 • Pocket organizers.
 • Cameras.
 • 1 to 2-cell hand-held devices
