Delivery robots

Last-mile consumer delivery of groceries, take-out food and online consumer items is the mission-critical task of these robots. While payloads vary in size and weight, these robots typically have longer run times than the moving class of robots and are typically powered by 48V to 100V batteries.

The power delivery network

The DCM converter series fits the needs for this class with operation from 43 – 154V input. The DCM3623 enables a regulated 24 or 48V distribution from the battery for servo drives, other payloads and downstream converters. The DCM3623 provides 240W of power at 90% efficiency from a 36 x 23 x 7.3mm package. With a 24 – 48V rail established, ZVS buck or buck-boost regulators can typically be used to power lower voltage rails.
