What are Point-of-Load converters?
Point-of-load converters (PoLs) are used in distributed power architectures (DPAs) to step down a relatively high power distribution bus voltage to the lower voltages needed by system components such as microprocessors, ASICs, and other digital ICs. DPAs are used in systems of all sizes to improve power distribution efficiency. Larger systems tend to use higher […]
