New power components improve charging in mobile devices and support high-voltage systems for robotics and industrial applications with lower heat and smaller size.
pSemi is expanding its power management lineup with two new components aimed at high-efficiency energy conversion in very different but converging markets: fast-charging mobile devices and compact high-power systems such as robotics and industrial electronics. The new parts—the PE26100 buck converter and PE25304 charge pump module—reflect a broader shift toward higher-voltage, higher-efficiency architectures in both consumer electronics and electromechanical systems.
At the center of the mobile charging update is the PE26100, a multi-level buck converter designed for direct battery charging in devices like smartphones and tablets. It supports up to 6A output and is optimized for thin form factors where thermal limits and board space are critical constraints. The device is designed to work across USB Power Delivery and PPS ecosystems, handling inputs from 4.5V to 18.5V and dynamically switching between 4-level and 3-level buck operation depending on input conditions. In PPS configurations, it can also operate as a fixed-ratio charge pump with selectable 2:1 or 3:1 conversion modes, improving flexibility in how power is delivered from USB sources to batteries.
The second device, the PE25304, targets a different class of applications: higher-voltage systems that require efficient step-down conversion in tight spaces. It is a switching-capacitor power module designed for 48V-based architectures, operating across a 20V to 60V input range and delivering a fixed 4:1 conversion ratio. With up to 72W output and efficiency reaching about 97%, it is positioned for applications such as dexterous robotics, particularly humanoid robotic hands, as well as drones, medical devices, and compact industrial systems where heat and volume constraints are significant design challenges.
Beyond these two products, pSemi is also extending its broader power portfolio with several related technologies. These include two-stage buck regulators for extremely low-voltage cores in advanced processors and optical transceivers, ultra-high-efficiency charge pump solutions for intermediate bus conversion, and integrated boost LED driver systems that combine charge pump and boost stages in a single package. Together, these address increasing demand for higher efficiency and lower thermal output in dense electronic systems.
