It's intelligent to design PSUs online
Microchip has set up an online intelligent power-supply design centre.
Microchip has set up an online intelligent power-supply design centre This comprehensive website provides the technical resources needed to design analogue power supplies, augment existing analogue power supply designs with inexpensive microcontrollers, or design switch-mode power supplies (SMPS) with full digital control of the power-conversion feedback loop

World's first serial EEPROM supporting ACR SIG
Microchip has announced the world's first serial EEPROM supporting the Advanced Communications Riser Special Interest Group (ACR SIG) specification.
Easy interfacing to faster microcontrollers
Microchip has added two new devices to its PIC16C92X family of 8bit one-time-programmable microcontrollers with integrated liquid-crystal display controller.
The site offers direct access to all of Microchip's power-supply application notes, reference designs and other technical documentation.
Links to Microchip simulation tools (including the Mindi simulation tool for battery charger and power-supply circuits) are also provided.
The intelligent power-supply design centre offers design tools for each of four levels of digital integration into power supplies.
Level one involves using an 8bit microcontroller to implement simple functions, such as soft start.
At level two, the control loop is still analogue, with an 8 or 16bit microcontroller providing basic proportional control.
The loop is also still analogue at level three, but an 8 or 16bit microcontroller or digital signal controller (DSC) can be used to modify the topology of the power supply.
At the highest level of digital integration into power supplies, the power-conversion loop is entirely digital and managed by a DSC with specialised peripherals.
Microchip has long provided cost-effective PIC microcontroller and analogue products to the power-supply market, and has recently announced a new family of dsPIC DSCs (dsPIC30F1010/2020/2023) for full digital control of SMPSs.
