STNRG011TR integrated digital controller
The STNRG011TR from STMicroelectronics is a highly integrated digital controller for switch-mode power supplies (SMPS) designed for high-efficiency AC-DC conversion applications requiring advanced power management and energy efficiency. This digital power controller combines a multi-mode PWM controller, power factor correction (PFC) stage, and resonant half-bridge controller in a single chip, operating with a 32-bit ARM Cortex-M0 core that enables sophisticated digital control algorithms for optimal power conversion efficiency across various load conditions. Housed in a compact 5x5 mm QFN32 package, the device supports input voltages up to 600V and switching frequencies up to 500 kHz, making it ideal for server power supplies, telecom infrastructure, industrial equipment, and high-end consumer electronics where high power density and energy efficiency are critical requirements. The STNRG011TR's digital architecture allows real-time monitoring and adaptive control of power parameters, including voltage, current, and temperature, providing designers with unprecedented flexibility in implementing complex power management strategies while meeting stringent energy efficiency standards such as 80 PLUS Titanium.
STNRG011TR Key Features
This digital power controller features an advanced hybrid control approach that combines fixed-frequency PWM for the PFC stage and variable-frequency resonant control for the DC-DC stage, achieving efficiency levels up to 96% at full load. The device incorporates a high-voltage start-up circuit that eliminates the need for external auxiliary power supplies during initial operation, and includes integrated 600V-rated half-bridge drivers with programmable dead-time control for safe operation. Key specifications include a digital PFC controller with average current mode control, a LLC resonant controller with adaptive burst mode operation for light-load efficiency, and comprehensive protection features including over-voltage, over-current, over-temperature, and brown-out protection. The STNRG011TR operates over an industrial temperature range of -40°C to +125°C and features a rich set of communication interfaces including I2C, SPI, and UART for system monitoring and configuration. The device's firmware-programmable architecture allows customization of control parameters, protection thresholds, and operational sequences without hardware modifications.
