PVM controllers simplify design & speed time-to-market

The ZSPM15xx’s digital control loop and compensation are pre-configured to provide customers with a fast time-to-market and an easy-to-design solution for high-performance, digitally controlled power supplies when combined with one of Würth’s WE-HCM family of high performance inductors and one of ZMDI’s integrated MOSFET power stage DrMOS products: ZSPM9000, ZSPM9010, ZSPM9015 or ZSPM9060. The ZSPM15xx controller’s flexible design allows users to easily select the over-current protection limit, output voltage rise time and control loop compensation via two external resistors to achieve the highest performance in their application.

The initial release will include six products designed to support applications for loads from 10 to 40A with popular bus voltages: 0.85, 1.0, 1.2, 1.5, 1.8 and 2.0V. ZMDI also provides BOMs and circuit board layouts to improve customer design cycles, reduce external component cost and minimise application footprint size.

Würth Elektronik’s WE-HCM series of high performance power inductors were chosen for their balance between size, efficiency and power handling. The devices offer the lowest core losses with MnZn material, high saturation current ratings and extremely low DCR losses. The inductors are also magnetically shielded and engineered for reliability.

“Customer requirements are highly diverse, and many customers have expressed their desire for a simple-to-use solution with the advantages that our digital power solution provides,” said Hensen Wong, Product Marketing Manager, Power Management Division, ZMDI. “With this simple, easy-to-design approach, ZMDI and Würth Elektronik are able to offer customers a fast time-to-market with high-performance digital PoL solutions in popular bus voltages and load capabilities up to 40A.”

“Our customers demand that components such as inductors should never be a bottleneck in the design cycle. Our solution offers an industry-leading part from a manufacturer focused on around-the-clock service and the reduction of lead times. This solution is a ideal fit with ZMDI’s new ZSPM15xx chipset as it minimises logistical headaches yet provides a high quality product that simply works,” commented Calvin Hwung, Partnership Marketing Manager, Würth Elektroink, eiSos division.
