TPS60212 具有超低操作电流的稳压 3.3V 50mA 低纹波充电泵
TPS60212 描述
The TPS6021x step-up, regulated charge pumps generate a 3.3-V ±4% output voltage from a 1.8-V to 3.6-V input voltage. These devices are typically powered by two alkaline, NiCd, or NiMH battery cells or by one primary lithium MnO2 (or similar) coin cell and operate down to a minimum supply voltage of 1.6 V. Continuous output current is a minimum of 100 mA for the TPS60210 and TPS60211, and 50 mA for the TPS60212 and TPS60213, all from a 2-V 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 2 uA while the output voltage is maintained at 3.3 V ±6%. This is lower than the self-discharge current of most batteries.
