The SS6610/SS6611 are high-efficiency step-up DC/DC converters, with a start-up voltage aslow as 0.8V, and an operating voltage down to 0.7V. Consuming only 20µA of quiescent current, these devices include 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.
1. High efficiency. (93% when VIN=2.4V, VOUT=3.3V, IOUT=200mA) 2. Output current up to 500mA. (SS6610 at VIN=2.4V and VOUT=3.3V) 3. Quiescent supply current of 20mA. 4. Power-saving shutdown mode (0.1μA typical). 5. Internal synchronous rectifier (no external diode required). 6. On-chip low-battery detector. 7. Low battery hysteresis
