Digital Power Control

APEC 2018

STNGR011 assures a high performance and robust solution for cost optimized SMPS• 20 pin Digital combo multi-mode PFC and time-shift LLC

resonant half bridge controller, specifically designed to meet all the requirements an SMPS needs to comply with.

• A digital 8 bit core is managing together with the SMED(State Machine Event Driven) peripherals the system through an algorithm stored in the ROM and a NVM memory is available for the application parameters.

STRG04STNRG328

The new STC architecture is ideal for space and energy critical applications in Data Centers. • Extremely efficient (>98.6%) and very high-

density (>200W/inch2) solution able to convert from the 54V/48V input to the 12V intermediate bus.

• STNRG328 and STRG04 are the key STCcomponents used to accurately control and manage all the application requirements and protection features.

Wireless Charging

Silicon Carbide Solutions for Electric Vehicles

•The 15W and 5W TX and RX pairs allow the implementation of fully Qi certified Wireless Charging Systems, compliant to the Extended Power Profile and Baseline Power Profile, respectively.• Solutions for Wearable: • 1W with 11mm RX coil; capable of Direct Charging, eliminating

the need for an external Battery Charging IC• 2.5W with 26m RX coil. • TX coil is 20mm in diameter for both.

• All TX have best in class idle power consumption while still providing Analog Ping and FOD

• The 15W RX has a TX mode up to 5W for unique Dual Function applications

SiC Technological Benefits vs. Conventional Silicon IGBT• Higher Performance

• Extremely low power losses• High efficiency at low current• Intrinsic SiC body diode (4 quadrant operation)

• Higher Operating Frequency• Lower switching losses• Excellent diode switching performance

• Higher Operating Temperature: 200 CSiC Advantages for Vehicle Electrification: • Mileage Extension, Smaller Battery, Fast & Efficient Charging

• From ~2% (high load) to ~8% (low load) efficiency gain on average

• ~7x lower switching losses• ~7x smaller chip size• ~40% lower total loss• ~ 5 - 10 times higher switching frequency

• Lower System Cost• ~5x reduced form factor• ~50% cooling system downsizing• Simpler sub-systems like smaller passives, no external

freewheeling diode,…
