The TPS65130/1 is dual-output dc-dc converter generaTIng a posiTIve output voltage up to 15 V and a negaTIve output voltage down to –15 V with output currents in a 200 mA range in typical applicaTIons, depending on input voltage to output voltage ratio. With a total efficiency up to 85% the device is ideal for portable battery powered equipment. The input voltage range of 2.7 V to 5.5 V allows the TPS65130/1 to be directly powered from a Li-Ion battery, from 3 cells NiMH/NiCd or alkaline batteries. The TPS65130/1 comes in a small 4 mm x 4 mm QFN-24 package. Together with a minimum switching frequency of 1.25 MHz it enables designing small power supply applications since it requires only a few small external components.
