| IC revision | C |
Description
The TPS6513x device is a dual-output DC-DC converter supply that generates a positive output up to 15 V and a negative output down to –15 V. The converter maintains low output voltage ripple. Typically, the maximum output currents are in the 200-mA to 500-mA range, depending on input voltage to output voltage ratio and the current limit option. The combined (VPOS and VNEG) efficiency reaches 85% to keep systems cool or achieve a longer battery-on-time. The input voltage range of 2.7 V to 5.5 V allows the devices to be powered from batteries or from fixed 3.3-V or 5-V rails.The converter operates with a fixed frequency PWM control topology and, when operating in power-save mode, uses a pulse-skipping mode at light-load currents. It operates with only 500-µA device quiescent current.Independent enable pins allow flexible power-up and power-down sequencing for both outputs. The positive and negative outputs operate independently, allowing for non-symmetrical output voltages and currents.The converter has an internal current limit, overvoltage protection, and a thermal shutdown for highest reliability under fault conditions. The converter is available in a 4-mm × 4-mm VQFN-24 package. The solution size is small with a minimum switching frequency of 1.25 MHz for smaller inductors and few other external components required.
