description
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.
