UCC25660x evaluation module for half bridge LLC

Overview

TopologyLLC Resonant Converter
Input voltage85-265 V
Output 112 V / 15 A
IC revisionA

Description

The UCC25660EVM-064 assists designers to evaluate the operation and performance of the UCC25660x LLC Resonant controller (16-pin SOIC package with removed pins for high voltage clearance). This evaluation module demonstrates how UCC25660x controls the LLC resonant half bridge DC-DC converter to achieve high efficiency throughout the load and input voltage range

Features

  • IPPC controlled (Input power proportional control) LLC resonant half-bridge DC-DC power conversion
  • DC line input from 365 VDC to 410 VDC
  • AC input voltage from 85 VDC to 265 VAC
  • Regulated 12-VDC typical output
  • Full-load power of 180 W, or full-load current of 15 A
  • High efficiency
  • Enhanced light load management:
  • High frequency pulse skip for improved light load efficiency
  • Low frequency burst for reduced standby power
  • Audible frequency range skip for reduced audible noise
  • User option to disable
  • Integrated PFC on/off control signal
  • Combined resonant current and resonant capacitor voltage sensing through one pin
  • Adaptive dead-time
  • X-capacitor discharge
  • Automatic capacitive region avoidance
  • Adaptive soft start with minimized inrush current
  • Complete sets of protections:
  • Cycle-by-cycle current limit, OCP1 protection
  • Configurable over power protection
  • OVP, internal & external OTP
  • Vin & VCC UVLO
  • Inbuilt 19.5 V VCC Clamp
  • Test points to facilitate device and topology evaluation

Typical applications

  • Multifunctional printer, Gaming console power supply, Enterprise and cinema projector, Power tools
  • Lighting
  • Industrial AC-DC adapters
  • SMPS power supply for TV, PC power supply
  • Medical power supply
