Digital Controllers Optimized for POLs

May 4, 2015 By admin Comments are Off , , , ,

ZMD AG (ZMDI) has released the ZSPM1511, ZSPM1512 and ZSPM1513 single-phase, true-digital pulse-width modulator power controllers optimized for non-isolated point-of-load (POL) applications. The ZSPM1511, ZSPM1512 and ZSPM1513 are pre-configured to provide customers with a fast time-to-market and easy-to-design solution for high-performance, digitally-controlled power supplies with one of ZMDI’s integrated MOSFET power stage DrMOS products: the ZSPM9000, ZSPM9010, ZSPM9015 or ZSPM9060. ZSPM15xx controllers feature 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.

ZSPM15xx controllers are preconfigured for the power stage output: the ZSPM1511 output is 0.85V; ZSPM1512 output is 1.00V; and ZSPM1513 output is 1.20V. All three new products are capable supporting up to a maximum load current of 15A. ZMDI provides bills-of-materials and circuit board layouts to improve customer design cycles, reduce external component costs and minimize the application footprint. Applications are expected to include: wireless base stations, enterprise routers/switches, gateways, cloud data storage, telecommunication equipment, and FPGA, DSP and SoC applications.

“The release of the ZSPM1511, ZSPM1512 and ZSPM1513 complements the ZSPM15xx family, which is able to provide power solutions for bus voltages from 0.85V up to 5.0V and maximum load currents up to 40A. Many high performance field programmable gate array(FPGA), digital signal processor(DSP) and system-on-chip(SoC) applications require multiple supply voltages to power the FPGA, DSP, SoC, peripheral input/output devices and transceivers in the application,” said Hensen Wong, Product Marketing Manager of the ZMDI Power Management Division. “With the ZSPM15xx family, ZMDI offers a wide portfolio of highly accurate digital power solutions with ultra-fast transient response, very low jitter and ripple, and they are simple to design with a turnkey solution.”
