Nisshinbo Micro Device Inc. R1700V
650 V Variable Output Current/Voltage ZVS PFC/LED Driver Controller
Overview
| Topology | Power Factor Correction |
| Input voltage | 8-650 V |
| Switching frequency | 0.5-100 kHz |
| Output 1 | 19 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
