Design of high-efficiency power supply for dishwashers

An ordinary dishwasher mainly consists of four modules: user interface, motor control, system management and connection. No matter which module, suitable semiconductor devices are needed. This solution adopts the Cortex-M series provided by NXP, covering all application requirements.
NXP provides complete ZigBee solutions, which integrate MCU and ZigBee transceiver, have the industry's lowest sleep power consumption and multiple software stacks. In addition, our various SMPS solutions support buck/boost or flyback topology, with standby power consumption as low as 10 mW, providing high efficiency and competitive BOM.

NXP's advanced triacs provide on-chip protection and excellent noise immunity to avoid false triggering. The Cortex-M series covers all application requirements and can meet design challenges such as:

complex appliance programs;
triacs directly connected to GPIO;
advanced TFT drivers (parallel or RGB);
reduce system costs by integrating high-performance analog modules such as 1% IRC.

In order to improve the interactive experience between customers and appliances, our display drivers support a wide range of display types and are suitable for many white goods applications. To ensure reliable interaction and low power consumption across the entire user interface, our capacitive touch ICs offer patented software algorithms, support self-calibration, and very low operating power consumption (less than 6uA)
