Silicon Laboratories has introduced an advanced digital power supply controller family. The Si825x family of single-chip controllers combine the flexibility and programmability of a DSP with the fast response of a hardware-based controller. This unique architecture enables the devices to provide both digital power control and power management functions for most isolated and non-isolated switch-mode power supply topologies while consuming one-tenth the space and drawing less than 15% of the supply current of typical DSP solutions, according to the company. The high-bandwidth control loop updates at 10 MHz and contains a dedicated ADC, programmable DSP filter engine, six-channel DPWM and programmable over-current protection. The system management controller performs fault detection and recovery, control loop optimisation, PMBus communication and external device management. The Si825x comes in 28-pin QFN and 32-pin LQFP package.
