applications
D Replaces DC/DC Converters With Inductors
in Battery-Powered Applications Like: − Two Battery Cells to 3.3-V Conversion − MSP430 Ultralow-Power Microcontroller
and Other Battery Powered Microprocessor Systems − Glucose Meters and Other Medical Instruments − MP3 Portable Audio Players − 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, 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 fo...
