TPS60204
- Regulated 3.3-V output voltage with up to 100-mA output current from a 1.8-V to 3.6-V input voltage
- Less than 5-mV (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
- 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
- Compact converter solution in ultrasmall 10-pin MSOP with only four external capacitors required
- Evaluation module available (TPS60200EVM-145)
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. Only four external capacitors are needed to build a complete 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.
