description
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
.
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-
A (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).
