产品概述

描述

The STNRG328S is a digital controller for STC/HSTC open loop resonant converter from STMicroelectronics. It performs a power conversion from an input voltage in a typical range of 40 V to 60 V to an output voltage with a programmable conversion ratio from 2:1 to 10:1 with fixed duty cycle and programmable frequency from 140 kHz to 300 kHz. It’s able to deliver an output power in the range from 500 W up to 2 KW with very high efficiency in wide load range and with efficiency peak of 98.4% .
A State Machine Event Driven (SMED) implements the control strategy to ensure all the STC/HSTC control functions, in particular the ZCD (Zero Current Detection) feature allows a management of the deadtime and the switching frequency in order to achieve the perfect LC resonance and top efficiency independently from the external component variations.
The STNRG328S firmware is specifically designed to program the SMED and implement the control strategy.
