Product Overview

STNRG328S is a digital controller for STC/HSTC open loop resonant converter from STMicroelectronics. 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. Typical application: server DC/DC intermediate bus generation from 40V to 60V input voltage, 200W to 2KW output power range.
  • Support wide conversion ratio from 2:1 to 10:1 to provide several Vout
  • Current limit in combination with Hot swap controller, operating input voltage window
  • Soft-start control, driver management, temperature control
  • 10bit ADC, UART interface, I2C fast/slow speed rate, GPIOs peripherals
  • Flash and EEPROM with read-while-write (RWW) and Error Correction Code (ECC)
  • Operating temperature range from -40°C to 105°C
  • VFQFPN32 package
  • RAM: 6Kbytes
  • Supply voltage range from -0.3 to 6.5V
  • Output low voltage at 5V is 0.5V maximum
