Description Absolute Maximum Ratings Parameter +In to -In +In to -In PC to -In TM to -In VC to -In +Out to -Out Isolation voltage The V048K020T080 V- I Chip Voltage Transformation Module (VTM) breaks records for speed, density and efficiency to meet the demands of advanced DSP, FPGA, ASIC, processor cores and microprocessor applications at the point of load (POL) while providing isolation from input to output. It achieves a response time of less than 1 µs and delivers up to 80 A in a volume of less than 0.25 in3 while providing low output voltages with unprecedented efficiency. It may be paralleled to deliver hundreds of amps at an output voltage settable from 1.1 to 2.3 Vdc. The VTM V048K020T080’s nominal output voltage is 2 Vdc from a 48 Vdc input factorized bus, Vf, and is controllable from 1.1 to 2.3 Vdc at no load, and from 1.1 to 2.2 Vdc at full load, over a Vf input range of 26 to 55 Vdc. It can be operated either open- or closed-loop depending on the output regulation needs of the application. Operating open-loop, the output voltage tracks its Vf input voltage with a transformation ratio, K = 1/24, and an output resistance, ROUT = 1.3 milliohm, to enable applications requiring a programmable low output voltage at high current and high efficiency. Closing the loop back to an input Pre-Regulation Module (PRM) or DC-DC converter can pensate for ROUT.
