TPS60100

Inside the latest state of the art DC/DC converter from Texas Instruments, two synchronous charge pumps work at 180 degree phase shift on one output. This clearly reduces the output ripple voltage.The TPS60100 has been designed especially for battery operated equipment using 1.8 V to 3.6 V batteries (two NiCd or NiMH cells). It delivers an output current up to 200 mA at 3.3 V and for this it needs only four external (SMD) capacitors. In this design there is no need for any over dimensioned, complicated or hard to come by chokes.The IC is contained in a thermally improved TSSOP housing, what the company calls a PowerPAD. By using a heatsink, a power loss of up to 25 W can be reached.
