Overview
Description
This AS048 2100W, single-plate induction cooktop design, using the iW248 smart IGBT driver and controller single-chip ASSP, offers high-efficiency and high-reliability performance. The design gives the flexibility to adjust the power in ±10W steps, which allows the users to cook at a simmering condition. The RL78/G15-based HMI card offers a low pin count, multiple matrix switches, LED indication, and a 7-segment display. Additionally, a capacitive touch sensing unit (CTSU) enables robust capacitive touch, which senses properly in wet conditions. Over-temperature detection using three negative temperature coefficient resistors (NTCs) is provided in the design.
Features
- Integrated ASSP design offers a low-cost, low-component-count system.
- AC input, IGBT voltage spike detection, and current sense using the iW248 help with fast protection response. It is a digital controller with analog driver blocks using a state machine that offers a much faster response.
- Patented low-power technology provides adjustability to ±10W, allowing users to cook at the simmer condition.
- Operates in constant current or constant power mode as per the VCE voltage detection.
- Three-temperature detection option with adjustable settings.
- Adjustable overvoltage cutoff and recovery register settings.

- AS048-EVK Energy Efficient Single Burner Induction Cooktop Reference Design
Hi I want to inquire about the voltage input in the design guide. The schematic shows 220-240 Vac in the user guide below However, another image on the website shows 90-265 Vac. Is it possible to power this with 110V? If yes, what output power is expected? Thanks
