SS6611G - Silicon Standard

SS6611G (SS6610G / SS6611G) High-efficiency Synchronous Step-up DC/DC Converter

The SS6610/11G are high-efficiency step-up DC/DC converters, with a start-up voltage as low 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 minim.
