Description
Product Overview
EVAL-LTM4638-AZ is an evaluation board to evaluate LTM4638 20VIN PolyPhase step-down µmodule regulator. This board is a power supply generating 1V, 60A (max) from a 3.1V to 20V input. It is a quad PolyPhase® solution featuring the LTM®4638, a high-performance and high-efficiency step-down regulator. The LTM4638 is a complete DC-to-DC point-offload (POL) regulator in a thermally enhanced 6.25mm × 6.25mm × 5.02mm BGA package. The EVAL-LTM4638-AZ is optimized using a default frequency of 600kHz, and the current mode control architecture allows easy current sharing. The LTM4638 operates in continuous-conduction mode (CCM) by default but can be placed in pulse-skipping mode (PSM) to optimize efficiency at light loads. An external clock IC, LTC6902, is included in the EVALLTM4638-AZ and is used to provide clock synchronization signals to interleave the four channels 90° out-of-phase for reduced root mean square (RMS) input current ripple and output voltage ripple.
- Current mode control: good current sharing
- External frequency synchronization
- Differential remote sensing
- 86.2% efficiency at VIN = 12V, VOUT = 1V, IOUT = 60A
