The XDP™ IDP2303A is a digital combination controller that integrates a driver and a 600V depletion-mode unit, specifically designed for boost PFC and half-bridge LLC target switched-mode power supplies (SMPS) ranging from 75W to 300W.
- Integrated startup unit to reduce standby power consumption.
- Supports multi-mode PFC operation to optimize the efficiency curve.
- Synchronous PFC and LLC burst mode control with soft start to prevent noise.
- Comprehensive parameters for configuring PFC and LLC operations.
- Configurable and comprehensive protection features for PFC/LLC/IC temperature.
- IEC62668-1 certified active X-CAP discharge function.
- Flexible IC parameter settings using a digital UART interface, supporting the PSU platform approach.
- No need for an auxiliary power supply.
- Low BOM quantity and small size design are achieved due to the high integration of digital control and the reduction of external components.
- Easy design of system schematic and PCB layout.
- Improved system reliability.
- Shorter development cycle and higher design and production flexibility.
- LCD TV power supplies.
- Conventional SMPS.
- Power adapters.
