TPS51124RGER Typical application Circuitry

TPS51124RGER

The TPS51124RGER is a key member of the TPS51124 series, known for its exceptional performance as a dual-synchronous step-down controller. This series is designed to efficiently convert higher input voltages into two separate lower output voltages, making the TPS51124RGER especially suited for powering core voltages in systems like notebooks, where efficiency and compact design are crucial.

1. Vin - Input Voltage Supply: The TPS51124RGER requires power through its Vin pin. It's essential to supply a voltage within the TPS51124RGER's specified operational range to this pin, ensuring the device's efficiency and longevity.

2. Vout1 and Vout2 - Dual Output Voltages (Regulated): The TPS51124RGER delivers two regulated output voltages through Vout1 and Vout2 pins. The device's ability to maintain stable voltages on both channels is crucial for the simultaneous operation of different system components.

3. GND - Ground Pin: The Ground pin (GND) on the TPS51124RGER acts as the common reference for the input and output voltages. A robust connection of this pin to the ground plane is crucial for the accurate and stable operation of the TPS51124RGER.

4. EN - Enable Pin Control: The enable pin (EN) on the TPS51124RGER allows users to control the operation of the converter, enabling or disabling it as required. This function is beneficial for power management, particularly in systems where conservation of energy is a priority.

5. FB1 and FB2 - Feedback Pins for Voltage Regulation: The feedback pins, FB1 and FB2, are critical for regulating the output voltages of the TPS51124RGER. Connecting resistor dividers from each output to its respective feedback pin enables precise setting of both output voltages, in accordance with the TPS51124RGER datasheet.

6. BOOT1 and BOOT2 - Bootstrap Pins for Enhanced Performance: The bootstrap pins, BOOT1 and BOOT2, are essential for improving the performance of the TPS51124RGER. These pins, usually connected to bootstrap capacitors, provide the necessary drive voltage for the high-side MOSFETs, crucial for efficient operation.

7. PGOOD - Power Good Output: The power good (PGOOD) pin is an open-drain output that goes high when both output voltages are within their nominal ranges, indicating the proper functioning of the TPS51124RGER. This feature is useful for system status monitoring.

In summary, the TPS51124RGER is an ideal solution for applications that require dual-channel, efficient power conversion in a compact space. Its features, including dual adjustable output voltages, enable control, enhanced performance through bootstrap pins, and real-time status indication, make the TPS51124RGER a versatile and essential component in sophisticated electronic systems. Correct implementation following the guidelines in the TPS51124RGER datasheet is crucial to fully exploit its capabilities and ensure optimal performance in your applications.
