Up until now engineers have always kept an eye on the driving factors for designing a new switching mode power supply. These are: EMC; heat generation; efficiency; system size and weight; system reliability; system costs; and time-to-market.
Designed for switching mode power supplies, the EPCOS CoolSet range combines the control IC and the avalanche rugged CoolMOS in one.
According to the company, key advantages are:
*Reduce surrounding components by factor 2.
*Reduce power dissipation by factor 2,5.
*Eliminate or minimise the size of heatsinks.
*Minimise PCB size.
*Reduce storage costs.
*Reduce time-to-market.
*Reduce system costs.
*Higher system reliability.
*Reduce EMI.
CoolSet includes the company’s evolutionary CoolMOS technology. This MOSFET technology actually reduces the area-specific RDS(on) for a 600 V MOSFET by a factor of 5 over any other previously existing technologies. In addition, the improvement this technology delivers is even greater at higher blocking voltages, according to the company.
Avalanche energy capability for CoolMOS transistors allows energy ratings to be increased to the maximum possible range with active zener clamping.
All of these benefits of CoolMOS are offered to within the CoolSet control IC.
The ICs’ features are: modulated gate drive; low start up current; input undervoltage lockout; maximum duty cycle limitation; thermal shutdown; and soft start.
CoolSet enables the implementation of power supplies with 1–200 W output powers with only a few standard packages: eg DIP 8, DIP 14, DIP 20, DSO 14, TO 220-7.
