3 Description
The TPS6513x 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 devices to
be powered from batteries or from fixed 3.3-V or 5-V
supplies. The TPS6513x comes in a small 4-mm × 4-
mm VQFN-24 package. Together with a minimum
switching frequency of 1.25 MHz, the device enables
designing small power supply applications because it
requires only a few small external components.
The converter operates with a fixed frequency PWM
control topology and, if power-save mode is enabled,
it uses a pulse-skipping mode at light-load currents. It
operates with only 500-µA device quiescent current.
Independent enable pins allow power-up and power-
down sequencing for both outputs. The device has an
internal current limit overvoltage protection and a
thermal shutdown for highest reliability under fault
conditions.
