Manufacturer: STMicroelectronics

Overview: STNRG328S Datasheet Digital controller for STC/HSTC topologies Product status link STNRG328S Product.

General Description

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% .
