RICOH Electronic Devices Co., Ltd. R1700V

650 V Variable Output Current/Voltage ZVS PFC/LED Driver Controller

Overview

TopologyPower Factor Correction
Input voltage8-650 V
Switching frequency0.5-100 kHz
Output 119 V / 0.27 A

Description

The R1700V is a zero-voltage switching (ZVS) PFC/LED driver controller with a variable output current/voltage. It is ideal for improving power factors of LED lightings and consumer appliances. This device features the arbitrary setting of output voltage based on buck-boost (inverting) topology. Integration of this device and the R1580N allows the twostage architecture and a flicker-free operation in LED lighting applications.

Features

  • Input Voltage Range: 8 V to 650 V
  • PWM Linear Dimming Control Range: 5% to 100%
  • Built-in Max. 650-V Operating Regulator
  • Built-in Half Bridge Gate Driver
  • Corresponding Topologies
  • Buck-boost (Inverting) PFC
  • Variable Output Current PFC, Linear Dimmable
  • Variable Output Voltage PFC
  • Boost PFC
  • Buck PFC

Typical applications

  • PFCs for PAM Controlled Motor Drivers / Low Output Voltage PFCs / DC/DC Converters
  • LED Lighting PFCs, Linear Dimmable / Flicker-free LED Lighting using R1580N
