Texas Instruments TPS63710DRRR
The TPS63710 is an inverting step-down dc-dc converter generating a negative outputvoltage down to -5.5 V. It provides an output current up to 1 A, depending on the input-voltage tooutput-voltage ratio. Its filtered reference system gives low 1/f noise which is required in highperformance telecommunication systems.
The TPS63710 operates with a fixed-frequency PWM control topology. It has an internalcurrent limit and a thermal shutdown. The input voltage range of 3.1 V to 14 V allows the TPS63710to be used in a variety of applications where a negative output voltage is generated from a, inabsolute value, higher positive input voltage.
Synchronous rectification provides high efficiency especially for small output voltageslike -1.8 V, which are typically used as a negative supply voltage for high performance DACs andADCs. A fixed switching frequency of 1.5 MHz allows the use of small external components andenables a small total solution size.
The TPS63710 comes in a 3-mm × 3-mm WSON package that provides good thermal performancein applications running at high ambient temperature.
