Dual-phase digital PWM power controller uses OTP/resistor programming

March 31, 2016 // By Graham Prophet
Integrated Device Technology has added a dual-phase digital power controller with features to optimise, monitor and control high-power supply systems. The second-generation ZSPM1363 digital PWM (pulse-width modulation) controller delivers performance and transient response, for telecommunications, server, storage, FPGA and infrastructure markets.

The chip’s extended one-time programmable (OTP) memory provides storage for multiple application configurations. The device’s flexibility and ease of reuse help reduce design time, and the highly integrated silicon requires few external components to help lower system cost. Developed using automotive design methodology, the chip is rugged and highly reliable, with operating temperatures up to 125°C.

 

The ZSPM1363 features simple resistor-based compensation adjustment after programming if load condition changes; there’s no need to reprogram the chip. And its multi-programmable compensation architecture achieves fast transient response while providing low ripple, steady state performance. The part occupies a 5 x 5 mm 32-QFN package.
