Description

The TPS65131-Q1 device is dual-outputdc-dc converter generating a positive output voltage up to 15 V and a negative output voltage downto –15 V with output currents of typically 200 mA, depending on input-voltage to output-voltageratio. With a total efficiency up to 85%, the device is ideal for portable battery-poweredequipment. The input-voltage range of 2.7 V to 5.5 V allows, for example, 3.3-V and 5-V rails topower the TPS65131-Q1 device. The TPS65131-Q1 device comes in a QFN-24 package with thermal pad.Requiring few and small external components, the overall solution size can be small.

The converter operates with a fixed-frequency PWM control topology and, with power-savemode enabled, uses a pulse-skipping mode at light load currents. In operation, the typical overalldevice quiescent current is only 500 µA. In shutdown, the device draws typically 0.2 µA.Independent enable pins allow power-up and power-down sequencing for both outputs. The device hasan internal current limit, overvoltage protection, and a thermal shutdown for highest reliabilityunder fault conditions.

The TPS65131-Q1 device is qualified for automotive applications, according to AEC-Q100temperature grade 2. The electrical characteristics are tested over –40°C to 125°C device junctiontemperature. This, combined with lowest shutdown currents, small solution size, package withthermal pad, plus good efficiency and protection features, targets automotive and industrialapplications.
