The TPS54526RSAT voltage regulators are part of the DC DC switching regulators family of Texas Instruments’ Power Management Integrated Circuits (PMIC) portfolio. Developed by TI, these voltage regulators offer high efficiency and low quiescent current, and are targeted for a range of end-equipment operating on intermediate bus voltages, such as data centers, industrial equipment, and network communications. This power management integrated circuit is designed to provide enhanced performance in applications where space is at a premium.

The TPS54526RSAT voltage regulators are adjustable current limiters that can be used to limit the inrush current during start up and reduce the inherent risk of blowing the system. They feature an adaptive voltage positioning (AVP) to help optimize system efficiency by managing load current and output voltage according to a pre-defined profile. The maximum operating current of the TPS54526RSAT is limited to 5A for robust operation.

The TPS54526RSAT voltage regulators support a wide input voltage (VIN) range from 4V to 20V, making them suitable for many popular power supplies. The switching frequency (fsw) is adjustable from 200kHz up to 1Mhz. This switching frequency can be adjusted to match external components such as inductors and capacitors to achieve the desired output voltage and ripple characteristics. This allows designers to reduce the total component count and board area.

The TPS54526RSAT voltage regulators feature a high efficiency buck configuration, allowing them to deliver higher levels of output current while still maintaining a low output voltage ripple. This high efficiency design also allows the device to operate with minimal heat dissipation, making it well suited for applications where space and power consumption are important. The integrated over current protection (OCP) helps to protect the system from potential damage due to overloads or faults.

The TPS54526RSAT voltage regulators also feature integrated soft-start circuitry for smooth start up and output voltage tracking for efficient system operation. The output voltage ramp-rate can be adjusted to ensure a smooth supply voltage transition from pre-start state to the desired output voltage. This feature also helps minimize input current spikes at the start-up and reduces the power loss caused by the inrush current.

The TPS54526RSAT voltage regulators can be used in a variety of applications, including distributed power systems, data centers, industrial equipment, consumer electronics, and computing and networking applications. The integrated over voltage protection (OVP) helps protect the system from unexpected shocks in the input voltage, while the adjustable over current protection limits the maximum output current delivered by the device. Additionally, the integrated output voltage accuracy of ±0.5% makes the TPS54526RSAT voltage regulators well suited for precision voltage control.

Overall, the TPS54526RSAT voltage regulators are an efficient and robust solution for supply voltage regulation in systems where space is at a premium. The wide input voltage range, adjustable switching frequency and integrated protection features make the TPS54526RSAT an ideal choice for many applications. The integrated high efficiency power stage design allows the device to deliver high levels of output current with minimal heat generation, making it suitable for a variety of different applications.
