Analog Devices LTM4683 | Demoboard EVAL-LTM4683-A1Z
Low VOUT Quad 31.25A (EVAL-LTM4683-A1Z) or Single 125A (EVAL-LTM4683-A2Z) µModule Regulator with Digital Power System Management
Overview
| Topology | Buck Converter |
| Input voltage | 4.5-14 V |
| Output 1 | 0.4 V / 30 A |
Description
The EVAL-LTM4683-A1Z evaluation board features the LTM4683: the wide input and output voltage range, high efficiency and power density, quad output PolyPhase® DCto-DC step-down µModule® (micromodule) regulator with digital power system management (PSM). The EVAL-LTM4683-A1Z evaluation board is configured as a 4-phase four outputs. A similar evaluation board with a 4-phase single output is also available (EVAL-LTM4683-A2Z).The EVAL-LTM4683-A1Z evaluation board’s default input voltage range is 4.5V to 14V. However, if VIN is lower than 6V and within 4.5V ≤ VIN ≤ 5.75V, a minor modification to certain existing on-board components is required.
Features
- Quad digitally adjustable analog loops with digital interface for control and monitoring.
- Optimized for low output voltage ranges.
- 15mm × 22mm × 5.71mm BGA package.
Typical applications
- Multi-Rail Processor Power, Configurable Core Power
