Applications

IDC2000 Applications for Power Supplies

Interconnectivity between the IDC2000 and a typical Power Supply

1. Each PSG Channel has two outputs: PSG & SPWM .
2. PSG port aimed for any desired sequential signal.
3. SPWM port can serve to generate a complementary signal for the PSG port signal for half bridge application or a PWM signal controlled by CPU (Software).
4. IDC2068 model drives up to 11 half bridges (Synchronous Buck), up to 5 full ridges, etc. for multiple voltage applications.

UPMC Multi-Phase Partitioning Application

1. Scalable to the required number of phases and to the power level.
2. Lower cost and minimum parts count
3. High noise immunity
4. Full power management
5. No power heat transferred into the controller
6. Configurable control algorithms
7. Allows control of additional multiphase and/or other types of power supplies
8. Higher efficiency
9. Premium performance

Example is based on output current measured on the output inductor and using half bridge blocks with integrated dumb drivers. Other current measurement methods and power components structures can be chosen.

Multi-Phase All-Ceramic VRM Application:

VI. DC-DC Converter Application

Another application that demonstrates the power of the UPMC is a multiphase buck converter operating at switching frequency of 6MHz per phase at the load step-up transient of 100A and a slope current of 1000A/µsec. The multiphase converter ( includes 4 HB legs driven and controlled by the IDC2100 which is a future upgrade version in the UPMC road map aimed for ultra-fast switching mode power supplies.

Four phase synchronized buck converter used for the simulation study. An approximate parameters simulation study was performed to compare the expected performance of the 4 phase converter in respect to a 6 phase converter alternative, amongst others to show the capabilities of the envisioned solutions. The 4 phase alternative operates at 200KHz and the 6 phase at 800KHz. In the IDC implementation the switching frequency rises to about 6MHz during the transients to achieve the targeted results.
