Regulated 3.3-V High-Power Low-Noise Charge Pump DC/DC Converter
The TPS60100 Step-up regulated Charge Pump generates a 3.3-V 4% output voltage from a 1.8-V to 3.6-V input voltage (two alkaline, NiCd, or NiMH batteries). Output current is 200 mA from a 2-V input. Only four external capacitors are needed to build a complete low-noise 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. From a 2-V input, the TPS60100 CAN start into full load with loads as low as 16 .
The TPS60100 features either constant frequency mode to minimize noise and output voltage ripple or the power-saving pulse-skip mode to extend battery life at light loads. The TPS60100 switching frequency is 300 kHz. The Logic shutdown function reduces the supply current to 1-uA (max) and disconnects the load from the input. Special current-control circuitry prevents excessive current from being drawn from the battery during start-up. This DC/DC converter requires no inductors and has low EMI It is available in the small 20-pin TSSOP PowerPADTM package (PWP).
