The Texas Instruments TPS63700DRCRG4 is an inverting buck-boost converter that generates a regulated negative output from a positive input rail. It delivers up to 360 mA with an adjustable output from -2V down to -15V. Switching at a fixed 1.38 MHz keeps the inductor small enough for space-constrained designs.
No synchronous rectifier is used, so the external Schottky diode selection matters for efficiency at higher output currents.
The TPS63700DRCRG4 shares the same base product number (TPS63700) and the same 10-VSON (3x3 mm) package as the TPS63700DRCR. Electrical ratings are identical — the suffix difference is packaging and reel quantity. Pin-compatible for the same PCB footprint.
