Description
TPS51980ARTVR Texas Instruments Dual Synchronous Step-Down PWM Buck Controller 4.5V-13.2V QFN32
Flexible Power Rails: 5 V to 12 V,
Reference: 800 mV 0.8% feature rich, single-channel synchronous-buck controllers that operates from a single 4.5-V to 13.2-V
Voltage Mode Control supply and can convert an input voltage as low as^
Support Pre-biased Startup 1.5 V.
Programmable Overcurrent Protection with The controller implements voltage mode control with Low-Side RDS(on) Current Sensing a fixed 300-kHz (TPS51113) and 600-kHz^
Fixed 300-kHz (TPS51113) and 600-kHz (TPS51163) switching frequency. The overcurrent (TPS51163) Switching Frequency (OC) protection employs the low-side RDS(on) current sensing and has user-programmable threshold. The
UV/OV Protections and Power Good Indicator OC threshold is set by the resistor from LDRV_OC
Internal Soft-start pin to GND. The resistor value is read when the^
Integrated High-Current Drivers Powered by over-current programming circuit applies 10uA of VDD current to the LDRV_OC pin during the calibration phase of the start-up sequence.
