- Backup-Battery Boost Converters
- Cordless Phones, PDAs
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, Ni Cd, or Ni MH battery cells or by one primary lithium Mn O2 (or similar) coin cell and operate down to a minimum supply voltage of 1.6 V. Continuous output current is a minimum of 100 m A for the TPS60210 and TPS60211, and 50 m A for the TPS60212 and TPS60213, all from a 2-V input.
