3.4  
The TPS60101 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 100 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  
TPS60101 can start into full load with loads as low  
as 33 Ω.

t – Time – µs  
The TPS60101 features either constant frequen-  
cy mode to minimize noise and output voltage  
ripple or the power-saving pulse-skip mode to  
extend battery life at light loads. The TPS60101  
switching frequency is 300 kHz. The logic  
shutdown function reduces the supply current to  
1-µA (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 PowerPAD  
package (PWP).
