description
The TPS60111 step-up, regulated charge pump
generates a 5-V
±4% output voltage from a 2.7-V
to 5.4-V input voltage (three alkaline, NiCd, or
NiMH batteries; or, one lithium or lithium ion
battery). Output current is 150 mA from a 3-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 3-V input, the TPS60111 can start
into full load with loads as low as 33
.
The TPS60111 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 TPS60111 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 cur-
rent 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).
