TPS60202 Datasheet | Texas Instruments

Features - 1 Regulated 3.3-V Output Voltage With up to 100-m A Output Current From a 1.8-V to 3.6-V Input Voltage - Less Than 5-m V (PP) Output Voltage Ripple Achieved With Push-Pull Topology - Integrated Low-Battery and Power-Good Detector - Switching Frequency Can Be Synchronized to External Clock Signal - Extends Battery Usage With up to 90% Efficiency and 35-μA Quiescent Supply Current - Reliable System Shutdown Because Output Capacitor Is Discharged When Device Is Disabled - Easy-to-Design, Low-Cost, Low-EMI Power Supply Since No Inductors Are Used - 0.05-μA Shutdown Current, Battery Is Isolated From Load in Shutdown Mode - pact Converter Solution in Ultra Small 10-pin MSOP With Only Four External Capacitors Required - Evaluation Module Available (TPS60200EVM-145) 2 Applications - Two Battery Cells to 3.3-V Conversion - MP3 Portable Audio Players - Battery-Powered Microprocessor Systems - Backup-Battery Boost Converters - PDAs, Organizers, and Cordless Phones - Handheld Instrumentation - Glucose Meters and Other Medical Instruments 3 Description The TPS6020x step-up, regulated charge pumps generate a 3.3-V ±4% output voltage from a 1.8-V to 3.6-V input voltage. The devices are typically powered by two Alkaline, Ni Cd or Ni MH battery cells and operate down to a minimum supply voltage of 1.6 V. Continuous output current is a minimum of 100 m A for the TPS60200 and TPS60201 and 50 m A for the TPS60202 and TPS60203, all from a 2-V input. Only four external capacitors are needed to build a plete low-ripple DC/DC converter. The push-pull operating mode of two single-ended charge pumps assures the low output voltage ripple as current is continuously transferred to the output.
