Description

1650 W LLC power supply optimized for compact chargers for electric three-wheelers, high-performance electric motorcycles and power tools, with constant voltage (CV) and constant current (CC) mode control using HiperLCS2-HB (LCS7269Z) half-bridge power device, HiperLCS2-SR (LSR2000C-H005) safety isolation device and HiperPFS-3 (PFS7539L) for power factor correction (PFC)

Features

HiperLCSTM2-HB LCS7269Z, HiperLCSTM2-SR LSR2000C-H005, HiperPFSTM-3 PFS7539LICs, CAPZero™-3 CAP300DG and InnoSwitchTM-3 EP INN3692C-H606 ICs

  • Integrated boost PFC and resonant LLC half-bridge (HB) plus synchronous rectification(SR)
  • Self-biased startup – no bootstrap required
  • Precise control of both SR and HB to optimize efficiency
  • 94% full load efficiency at 230 VAC

  • Up to 360 kHz switching frequency for LLC minimizes transformer size
  • Boost PFC input stage, PF >0.99
  • Optimized for battery charging
  • Option for external CC/CV control
  • Wide output voltage range: 26 - 60 VDC
  • Better than ±1% constant voltage (CV) regulation
  • Wide output battery current range: 0 A to 24 A
  • Better than ±5% constant current (CC) regulation

Typical applications

  • EV charger
