2 / 29 page TPS60130, TPS60131, TPS60132, TPS60133 REGULATED 5V, 300 mA HIGH EFFICIENCY CHARGE PUMP DC/DC CONVERTERS SLVS258A − NOVEMBER 1999 − REVISED DECEMBER 1999 2 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 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. Special current-control circuitry prevents excessive current from being drawn from the battery during startup. This dc/dc converter requires no inductors and therefore EMI is of low concern. It is available in the small, thermally enhanced 20-pin PowerPAD t package (PWP). 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 GND GND ENABLE FB OUT C1+ IN C1− PGND PGND GND GND LBI LBO OUT C2+ IN C2− PGND PGND PWP PACKAGE (TPS60130/TPS60132) (TOP VIEW) 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 GND GND ENABLE FB OUT C1+ IN C1− PGND PGND GND GND NC PG OUT C2+ IN C2− PGND PGND PWP PACKAGE (TPS60131/TPS60133) (TOP VIEW) Thermal Pad AVAILABLE OPTIONS TA PART NUMBER† PACKAGE DEVICE FEATURES TPS60130PWP 3-cell to 5 V, 300 mA Low battery detector −40 °C to 85°C TPS60131PWP PWP 20-Pin thermally 3-cell to 5 V, 300 mA Power good detector −40 °C to 85°C TPS60132PWP PWP 20-Pin thermally enhanced TSSOP 3-cell to 5 V, 150 mA Low battery detector TPS60133PWP enhanced TSSOP 3-cell to 5 V, 150 mA Power good detector † The PWP package is available taped and reeled.
