ZSPM1509 True-Digital PWM Controller IC for powering networking, communication, and industrial applications

ZMD AG (ZMDI), an award-winning global semiconductor company headquartered in Dresden, Germany, and specializing in enabling energy-efficient solutions, today announces the ZSPM1509 single-phase, true-digital pulse-width modulator (PWM) power controller optimized for powering next generation networking, communication and industrial equipment. It is pre-configured for a power stage output of 5.0V and is capable of supporting loads up to 10A.

ZMDI offers superior solutions for power management, sensing, battery management, automotive ASICs and industrial ASSPs. An analog mixed-signal company, ZMDI designs solutions for automotive, industrial, medical, information technology and consumer applications. With over 50 years of industry leadership, ZMDI is recognized for extensive system expertise that helps customers develop highly efficient solutions and minimize time-to-market for power management products.

In many networking, communication, and industrial systems, there are embedded field programmable gate arrays (FPGAs) or system-on-chips (SOCs). The FPGA or SOC typically requires multiple voltage rails to power up. With the introduction of the ZSPM1509 to the ZSPM15xx family, ZMDI has expanded the family to enable powering commonly used industry voltage rails from 0.85V to 5.0V. The ZSPM15xx family is optimized for ZMDI’s integrated MOSFET power stage DrMOS products to provide customers with high performance power solutions and fast time-to-market. ZMDI provides recommended bills-of-materials (BOMs) and printed circuit board (PCB) layout files to reduce external component cost and minimize the application footprint.

The ZSPM15xx family of digital controllers features a flexible design that 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 ZSPM1509 provides a highly accurate and efficient power conversion with low noise and ripple that is essential for many FPGAs or SOCs,” said Hensen Wong, Product Marketing Manager of the ZMDI Power Management Division. “With ZMDI’s Tru-sample™ technology, the ZSPM15xx family is capable of acquiring fast, accurate and continuous feedback on the output voltage so that it can react quickly to any change. This reduces phase-lag that is caused by sampling delays. In addition, it reduces noise sensitivity and improves transient performance.”
