description

The TPS6013x step-up, regulated charge pumps generate 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 Lilon battery). The output current is 300 mA

for the TPS60130/ TPS60131 and 150 mA for the TPS60132/ TPS60133, all from a 3-V input. Only four external

capacitors are needed to build a complete high efficiency dc/dc charge pump converter. To achieve the high

efficiency over a wide input voltage range, the charge pump automatically selects between a 1.5x or doubler

conversion mode. From a 3-V input, all ICs can start with full load current.

SLVS258A − NOVEMBER 1999 − REVISED DECEMBER 1999 description (continued) The devices feature the power-saving pulse-skip mode to extend battery life at light loads. TPS60130 and TPS60132 include a low-battery comparator; TPS60131 and TPS60133 feature a power-good output. The logic shut-down function reduces the supply current to 1 µA (max) and disconnects the load from the input.

SLVS258A − NOVEMBER 1999 − REVISED DECEMBER 1999 adaptive mode switching (continued) The voltage on the flying capacitors is measured and compared with the supply voltage VI. If the voltage across the flying capacitors is smaller than half of the supply voltage, then the charge pump switches into the 1.5x conversion-mode. The charge pump switches back from a 1.

SLVS258A − NOVEMBER 1999 − REVISED DECEMBER 1999 low-battery detector (TPS60130 and TPS60132) (continued) LBO is an open drain output. An external pullup resistor to OUT, in the 100-kΩ to 1-MΩ range is recommended. During start-up, the LBO output signal is invalid for the first 500 µs. LBO is high impedance when the device is disabled.
PAGE 7
SLVS258A − NOVEMBER 1999 − REVISED DECEMBER 1999 Power-Good detector (TPS60131 and TPS60133) The PG pin is an open-drain output that is pulled low when the output is out of regulation. When the output voltage rises to about 90% of its nominal voltage, power-good output is released. PG is high impedance when the device is disabled. An external pullup resistor must be connected between PG and OUT.

SLVS258A − NOVEMBER 1999 − REVISED DECEMBER 1999 APPLICATION INFORMATION capacitor selection (continued) Tables 3 and 4 lists the manufacturers of recommended capacitors. In most applications surface-mount tantalum capacitors will be the right choice. However, ceramic capacitors provide the lowest output voltage ripple due to their typically lower ESR. Table 3.
PAGE 18
SLVS258A − NOVEMBER 1999 − REVISED DECEMBER 1999 APPLICATION INFORMATION board layout Careful board layout is necessary due to the high transient currents and switching frequency of the converter. All capacitors should be soldered in close proximity to the IC. Connect ground and power ground pins through a short, low-impedance trace. A PCB layout proposal for a two-layer board is given in Figure 23.
PAGE 19
SLVS258A − NOVEMBER 1999 − REVISED DECEMBER 1999 APPLICATION INFORMATION application proposals paralleling of two TPS6013x to deliver 600 mA total output current Two TPS60130x devices can be connected in parallel to yield higher load currents. The circuit of Figure 25 can deliver up to 600 mA at an output voltage of 5 V.
PAGE 20
SLVS258A − NOVEMBER 1999 − REVISED DECEMBER 1999 APPLICATION INFORMATION TPS6013x operated with ultra-low quiescent current Because the output of the TPS6013x is isolated from the input when the devices are disabled, and because the internal resistive divider is disconnected in shutdown, an ultra-low quiescent current mode can be implemented.
