TPS60212 Datasheet | Texas Instruments

features D Regulated 3.3-V Output Voltage From a 1.8-V to 3.6-V Input Voltage Range D Ultra Low Operating Current in Snooze Mode, Typical 2 µA D Less Than 5-m V(PP) Output Voltage Ripple Achieved With Push-Pull Topology D Integrated Low-Battery and Power-Good Detector D Switching Frequency Can Be Synchronized to External Clock Signal D Extends Battery Usage With up to 90% Efficiency and 35-µA Quiescent Current D Easy-To-Design, Low Cost, Low EMI Power Supply Since No Inductors Are Used D pact Converter Solution in Ultra Small 10-Pin MSOP With Only Four External Capacitors Required - description D Evaluation Module Available (TPS60210EVM-167) 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, 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.
