10 pcs : TPS63710DRRR - Switching Voltage Regulators Low Noise, 1A Synch Invert Buck Convert

TPS63710 Inverting Step-Down DC-DC Converter Texas Instruments TPS63710 Inverting Step-Down DC-DC Converter generates a negative output voltage down to -5.5V and provides an output current up to 1A, depending on the input voltage to output-voltage ratio. The device's filtered reference system gives low 1/f noise which is required in high-performance telecommunication systems. The TPS63710 operates with a fixed-frequency PWM control topology. The device has an internal current limit and a thermal shutdown. The input voltage range of 3.1V to 14V allows the TPS63710 to be used in a variety of applications where a negative output voltage is generated from a, in absolute value, higher positive input voltage. Synchronous rectification provides high efficiency, especially for small output voltages like -1.8V, which are typically used as a negative supply voltage for high-performance DACs and ADCs. A fixed switching frequency of 1.5MHz allows the use of small external components and enables a small total solution size.
