TPS65130RGET Datasheet PDF - TI

●The TPS65130RGET is a dual-output DC-DC Converter generating a positive output voltage up to 15V and a negative output voltage down to -15V with output currents in a 200mA 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 to 5.5V allows the device to be powered from batteries or from fixed 3.3 or 5V supplies. Together with a minimum switching frequency of 1.25MHz, 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 500µA device quiescent current. Independent enable pins allow power-up and power down sequencing for both outputs.

● Up to 89% efficiency at positive output voltage rail

● Up to 81% efficiency at negative output voltage rail

● Power-save mode for high efficiency at low load currents

● Independent enable inputs for power-up and power-down sequencing

● Control output for external PFET to support completely disconnecting the battery

● Thermal shutdown

● Overvoltage protection on both outputs
