Description

This small and simple: low-noise inverting power module design (voltage inverter) cleanly supports a –5-V output voltage at up to 1.5 A of current from a 3- to 11.5-V input. Featuring TI’s TPS82130 MicroSiP™ power module step-down converter in an inverting buck-boost topology: the design achieves a power density of 584 mW/mm3 and a solution size of less than 50 mm2: allowing it to power sensitive analog loads in space-constrained: high-temperature communications equipment: such as optical modules. This design also supports many common industrial equipment: including those that require a 5-V input and –5-V output voltage inverter at up to 1 A.
