Description:
The TPS546D24A is a highly integrated, non-isolated DC/DC converter capable of high frequency operation and 40-A current output from a 7-mm × 5-mm package. Two, three, and four TPS546D24A devices can be interconnected to provide up to 160 A on a single output. The device has an option to overdrive the internal 5-V LDO with an external 5-V supply via the VDD5 pin to improve efficiency and reduce power dissipation of the converter.The TPS546D24A uses a proprietary fixed-frequency current-mode control with input feedforward and selectable internal compensation components for minimal size and stability over a wide range of output capacitances.
Features:
• Split rail support: 2.95-V to 16-V PVIN; 2.95-V to 18-V AVIN (4-VIN VDD5 for switching)
• Integrated 4.5-mΩ/0.9-mΩ MOSFETs
• Average current mode control with selectable internal compensation
• 2×, 3×, 4× stackable with current sharing up to 160A, supporting a single address per output
• Selectable 0.5-V to 5.5-V output via pin strap or 0.25-V to 5.5-V using PMBus VOUT_COMMAND
• Extensive PMBus command set with telemetry for VOUT, IOUT and internal die temperature
• Differential remote sensing with internal FB divider for < 1% VOUT error –40°C to +150°C TJ
• AVS and margining capabilities through PMBus
• MSEL pins pin programming PMBus defaults
• 12 Selectable switching frequencies from 225 kHz to 1.5 MHz (8 pin-strap options)
• Frequency sync in/sync out
• Supports prebiased output
• Supports strongly coupled inductor
