DESCRIPTION

· The STNRGPF02/12 integrates an Inrush Current Limiter function.

· STNRGPF12 provides digital inrush current control, generating two PWM signals to drive the input semi-controlled bridge.

FEATURES

· Embedded digital inrush current limiter and interleaved PFC digital controller.

· Two interleaved channels PFC with continuous conduction mode and fixed frequency operation.

· Average current mode control and mixed signal architecture.

· Soft start-up management, burst mode support, and feed forward for load and input voltage.

· Channel current balance function and programmable phase shedding.

· Status indicators for cooling system, PFC Fault, and PFC OK.

· Configurable driver via dedicated graphic tool with programmable fast overcurrent and thermal protection.

· Serial communication port for device programming and PFC parameters monitoring.

· Embedded memory includes 32 Kbytes flash, 1 Kbyte E2PROM, and 6 Kbytes RAM.

· Communication interfaces support UART asynchronous protocol.

· Operating temperature range from -40°C to 105°C.

APPLICATIONS

· Suitable for applications over 600 W including welding, air conditioners, and industrial motors.

· Used in UPS, chargers, and high power systems.

· Customizable firmware and configuration via eDesign suite.
