Description
General part information
STNRG328 Series
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.
