What is MAX5980AGTJ+ used for?
MAX5980AGTJ+ is used in network switches, telecom base stations, and server power supplies requiring simultaneous control of 4 independent DC-DC converter channels from a single 60 V input bus. Its 400 kHz switching frequency reduces the size of output inductors and filter capacitors, enabling compact power module designs with high power density. The device also suits industrial automation equipment and multi-rail embedded systems where centralized 4-channel power sequencing and fault protection are required.

Frequently Asked Questions
How does MAX5980AGTJ+ manage 4 independent power channels simultaneously at up to 60 V?
MAX5980AGTJ+ integrates 4 independent power-device control channels, each capable of operating on input voltages up to 60 V. The controller manages gate drive timing and protection for all 4 channels from a single IC, reducing the component count compared to using 4 discrete controllers. At 400 kHz switching frequency, each channel can drive external FETs to regulate output voltages with fast transient response. Independent fault flags per channel allow the host system to isolate a failing rail without disrupting the remaining 3 channels, making it well-suited for multi-rail server and telecom power architectures.
For a telecom power supply operating at -48 V bus, how does the 60 V rating of MAX5980AGTJ+ provide design headroom?
Telecom systems use a nominal -48 V bus that can swing from -36 V to -72 V under fault conditions. MAX5980AGTJ+'s 60 V input rating covers the full regulated -36 V to -60 V range, and with appropriate protection circuitry, the device can handle the transient peaks encountered on -48 V distribution buses. The 4-channel control allows simultaneous management of multiple output rails (such as 3.3 V, 5 V, 12 V, and 24 V) from the -48 V input, and the 400 kHz switching frequency reduces input ripple current, helping maintain stability across the full -48 V bus voltage range.
What thermal advantage does the TQFN-32 package with exposed pad provide in a high-density power board?
The TQFN-32 package of MAX5980AGTJ+ measures 5 mm × 5 mm with a central exposed thermal pad that directly contacts the PCB copper plane, providing a low-resistance thermal path with junction-to-board thermal resistance typically below 20°C/W. In a 4-channel power controller switching at 400 kHz, the exposed pad dissipates internal power losses efficiently without requiring additional heatsinking. This allows the MAX5980AGTJ+ to operate at ambient temperatures up to 85°C with minimal derating, supporting high-density power board layouts where 32 pins are routed in a 5 mm × 5 mm footprint alongside other ICs.
When is MAX5980AGTJ+ a more efficient solution than using 4 discrete single-channel controllers for multi-rail power design?
Using 4 discrete single-channel controllers requires 4 separate ICs, consuming 4 times the PCB area and 4 separate sets of compensation, enable, and feedback resistor networks. MAX5980AGTJ+ integrates all 4 channels into a single TQFN-32 (5 mm × 5 mm) package, reducing total IC footprint by approximately 60% and cutting passive component count. Power sequencing across all 4 channels is coordinated within the single IC, simplifying firmware and eliminating inter-IC timing skew. For multi-rail telecom or server designs requiring simultaneous 4-rail startup within 1 ms to 10 ms windows, the integrated solution offers lower design risk and faster time-to-market.
