Product Description
STMicroelectronics STNRG328S is an advanced AC/DC converter digital controller housed in a 14-pin VFQFPN-32 package with dimensions 5mm by 5mm. It is designed for STC/HSTC open loop resonant converter applications, converting an input voltage range of 40V to 60V to a programmable output with high precision and efficiency.
The device supports a programmable conversion ratio between 2:1 and 10:1 with a fixed duty cycle and frequency adjustable from 140 kHz to 300 kHz. It incorporates 10-bit ADC, UART, GPIO interfaces, and I2C Master to facilitate flexible communication and control in power management systems.
A key feature is the State Machine Event Driven (SMED) control that manages ZCD (Zero Current Detection) which optimizes switching timing to minimize losses and maintain perfect LC resonance, achieving up to 98.4% peak efficiency across a broad load range.
Operating reliably between -40°C and 105°C, the STNRG328S is suitable for various industrial, commercial, and electronic applications requiring efficient AC/DC power conversion. It complies with RoHS standards ensuring lead-free manufacturing and environmental safety.
This surface-mount package with 14 pins enables integration into compact and high-density electronic designs. The device’s firmware is specifically tailored to implement the SMED control strategy, enhancing stable performance under varying external component conditions.
Designed for STC/HSTC resonant converters and digital control. Wide input voltage range of 40V to 60V with highly programmable output. High switching frequency range from 140 kHz to 300 kHz for efficiency. Equipped with multiple digital interfaces: UART, GPIO, I2C Master.
Advanced SMED control strategy with zero current detection. RoHS compliant and suited for harsh industrial environments. Compact VFQFPN-32 package for surface mounting with 14 pins.
The STNRG328S enhances power efficiency and control precision in industrial electronics, laboratory power supplies, electric vehicles, and renewable energy systems. Browse the AC/DC Converter category at EnvMart for related STMicroelectronics products and trusted power management solutions.
