Single-phase PWM controller IC is fully configurable
ZMDI customers are already familiar with the advantages of the ZSPM1000 true-digital PWM controller solution. Like the ZSPM1000, the new ZSPM1005 has a digital control loop and is fully programmable, enabling fast design-cycles and easy debugging. For both products, ZMDI’s digital control engine provides best-in-class step-response performance resulting in the highest power density and best POL solution cost.
The new ZMDI controller includes a 2-pin-configuration feature to set output voltage, compensation, and other parameters using external resistors. The pin assignments are fully programmable by the Pink Power Designer software during development. In the final application, the ZSPM1005 controller device has the flexibility to configure a curve fitting relationship between the voltage at the configuration pins and parameters such as the output voltage set-point, so digital communication with the DC/DC converter for monitoring or on-the-fly configuration is not required. Since this "hybrid" IC is pin-to-pin compatible with the ZSPM1000, ZMDI’s family concept enables POL power module platform designs for modules with and without digital PMBus communication.
The company said it calls the new product a "hybrid" controller because it delivers the performance and flexibility of the digital world, while in the final application, it is used like a traditional analog-controller-based POL solution. Thus it provides a simplicity of use that makes it the ideal solution for POL power module requirements for FPGA designs.
Benefits of the ZSPM1005 include:
- Fast configuration and design flexibility improve time-to-market;
- Simplified design and integration;
- FPGA designer-friendly solution;
- Highest power density with smallest footprint;
- Pin-to-pin compatible with the ZSPM1000 PWM controller, enabling POL power module platform designs with or without digital communication;
- Higher energy efficiency across all output loading conditions.
The ZSPM1005 is in full production. Samples and the ZSPM8001 Evaluation Kits are now available.
For 5,000 pieces, the ZSPM1005 is priced at EUR 1,68 or USD 2.35 per unit.
