Product Overview

EVL6591-90WADP board is to evaluate a 90W ac/dc asymmetrical half bridge adapter using L6591 and L6563. The converter comprises a two stage approach, a PFC front end stage using the L6563 TM PFC controller with boost topology working in transition mode and a DC/DC stage that implements the asymmetrical half bridge topology driven by the L6591, the new PWM controller dedicated to this architecture. The L6563 integrates all the functions and protection needed to control the stage and an interface with the downstream DC/DC converter. The L6591 includes a current mode PWM controller, gate drivers for both low and high side MOSFETs with integrated bootstrap diode and all functions and protections tailored for this topology. This adapter uses magnetizing current and output inductor current ripple to obtain correct primary current direction to achieve zero voltage switching at turn on of both MOSFETs. The system offers good electrical performance with a low voltage and high current output.
  • Input mains range of 88Vrms to 264Vrms, frequency of 45Hz to 66Hz
  • Output of 12Vdc, 7.5A
  • No load: pin below 0.35W
  • Short circuit, overload, output overvoltage, brownout protections
  • Safety: according to EN60065
  • EMI: according to EN50022 class B
