The TPS63710DRRR from Texas Instruments is a low-noise synchronous inverting buck converter that generates a negative output voltage down to -5.5V from a 3.1V to 14V positive input. With up to 1A output current, fixed 1.5 MHz switching frequency, and filtered reference system for low 1\/f noise, it is designed for negative-rail power supplies in telecom, optical, and precision analog applications. Packaged in a 3\u00d73 mm WSON-12 with PowerPAD.<\/p>\n

Its filtered reference system achieves 22 \u00b5VRMS output noise (10 Hz-100 kHz), making it ideal for negative-rail supplies in precision ADCs\/DACs, GaN bias, and optical modules. The 1.5 MHz fixed frequency and 3\u00d73 mm WSON-12 package enable compact, low-noise negative-rail solutions.","working_principle":"The TPS63710DRRR uses an inverting buck topology to generate a negative output voltage from a positive input. During the on-time, the high-side switch connects the inductor to VIN, storing energy in the inductor. During the off-time, the synchronous rectifier (low-side switch) connects the inductor to the negative output, transferring energy to the output capacitor and load. The output voltage is regulated by comparing the FB pin (connected to a resistor divider from VOUT to GND) with an internal reference. The filtered reference system reduces 1\/f noise at the output. The constraint |VOUT| < 0.7 \u00d7 VIN must be satisfied for proper regulation. The 1.5 MHz switching frequency allows small inductor and capacitor values, while the integrated synchronous rectifier eliminates the need for an external catch diode.","pin_description":"\n
