60V 6A buck Charge pump-based DC/DC Converter Module
XM981A series is an Ultra-thin High Efficiency integrated power module which combines a 72W buck charge pump-based DC-DC converter with components.
This Module is a buck charge pump that outputs one-quarter of the input voltage, only three peripheral components are required to provide output power with a maximum efficiency of 96.5%.
Input voltage range is 20V to 60V, the maximum output current is 6A. It perfectly supports 12V intermediate bus from 48V systems.Compared to DC/DC converters that use inductors, the XM981A is ideal for applications that require high efficiency in a small footprint and low profile.
The XM981A also supports parallel connection, allowing up to 4 parallel connections (6A x 4 parallel = 24A), making it usable in applications requiring higher power.
