The TPS60210DGS is a regulated low-ripple charge-pump with ultra low operating current. It generates a 3.3V±4% output voltage from a 1.8 to 3.6V input voltage. Continuous output current is a minimum of 100mA for the TPS60210, all from a 2V input. Three operating modes can be programmed using the SNOOZE\ pin. When SNOOZE\ is low, the device is put into snooze mode. In snooze mode, the device operates with a typical quiescent current of 2µA while the output voltage is maintained at 3.3V±6%. This is lower than the self-discharge current of most batteries. Load current in snooze mode is limited to 2mA. When SNOOZE\ is high, the device is put into normal operating mode. During normal operating mode, the device operates in the newly developed linskip mode where it switches seamlessly from the power saving pulse-skip mode at light loads to the low-noise constant-frequency linear-regulation mode once the output current exceeds the linskip current threshold of about 7mA.
