The TPS51124 from Texas Instruments is a dual, adaptive on-time D-CAP mode synchronous buck controller. It is designed to enable system designers to cost-effectively complete notebook power bus regulators with minimal external components and low standby consumption.
This controller supports a wide input voltage range from 3 V to 28 V and output voltages from 0.76 V to 5.5 V. It features fixed frequency emulated on-time control, which allows for seamless operation between PWM mode at heavy loads and reduced frequency operation at light loads for high efficiency down to the milliampere range. The D-CAP mode is optimized for low ESR output capacitors, promising fast transient response without external compensation.
The TPS51124 is available in a 24-pin VQFN package measuring 4 mm x 4 mm. It operates within an ambient temperature range of -40°C to 85°C. The device includes separate power good signals for each channel, allowing for flexible power sequencing. It also features low-side RDS(ON) loss-less current sensing and adaptive gate drivers with an integrated boost diode.
Applications for the TPS51124 include notebook I/O and low-voltage system buses. Its high efficiency, low-power consumption, and shutdown capabilities make it suitable for various power management needs.
The input voltage range is 3 V to 28 V.
The output voltage range is 0.76 V to 5.5 V.
