ZMDI ZSPM1000 True Digital PWM Controller and ZSPM9000 DrMOS Device

ZMDI announced the ZSPM1000 True Digital PWM Controller and the ZSPM9000 DrMOS Device. The ZSPM1000 is a configurable digital power management system controller for high-current nonisolated DC/DC supplies. It operates as synchronous step-down converter in a single-rail and single-phase configuration. The ZSPM9000 DrMOS is a fully optimized, ultra compact, integrated MOSFET plus driver power stage solution for high-current, high-frequency, synchronous buck DC-DC applications. The ZSPM1000 controller and the ZSPM9000 DrMOS are available now. The chipset is priced at $3.21 (2.12 €) for 10,000 units. The chipset is ideal for smart power management applications.
