Manufacturer: Texas Instruments

Overview: TPS60204, TPS60205 REGULATED 3.3ĆV, 100ĆmA LOWĆRIPPLE CHARGE PUMP LOW POWER DC/DC CONVERTERS SLVS354A − FEBRUARY 2001 − REVISED SEPTEMBER.

General Description

D pact Converter Solution in UltraSmall 10-pin MSOP With Only Four External Capacitors Required D Evaluation Module Available (TPS60200EVM-145) applications D Replaces DC/DC Converters With Inductors in Battery Powered Applications Like: − Two Battery Cells to 3.3-V Conversion − MP3 Portable Audio Players − Battery-Powered Microprocessor Systems − Backup-Battery Boost Converters − PDA’s, Organizers, and Cordless Phones − Handheld Instrumentation − Glucose Meters and Other Medical Instruments 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, NiCd, or NiMH battery cells and operate down to a minimum supply voltage of 1.6 V.

Continuous output current is a minimum of 100 mA from a 2-V input.

Key Features

  • D Regulated 3.3-V Output Voltage With up to 100-mA Output Current From a 1.8-V to 3.6-V Input Voltage D Less Than 5-mV(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 Supply Current D Easy-to-Design, Low Cost, Low EMI Power Supply Since No Inductors Are Used D 0.05-µA Shutdown Current, Battery is Isola.
