RICOH Electronic Devices Co., Ltd. R1700 | Demoboard R1700

R1700 Series 650 V Variable Output Current/Voltage ZVS PFC/LED Driver Controller

Overview

TopologyBoost Converter
Input voltage8-650 V
IC revision2

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 two-stage architecture and a flicker-free operation in LED lighting applications.

Features

  • Overcurrent Protection (OCP)
  • Thermal Shutdown (TSD)
  • BST/VCC Pin Undervoltage Lockout (UVLO)
  • VCC Pin Overvoltage Lockout (OVLO)
  • Overvoltage Protection (FBOVP)
  • Latch-type Protection (Selectable)

Typical applications

  • LED lighting
  • Motor Drivers
