Product Introduction

Overview

The NCP1606BDR2G is a cost-effective power factor controller designed by ON Semiconductor. It is specifically tailored for use as a pre-converter in electronic ballasts, AC-DC adapters, and other medium power offline converters, typically up to 300 W. The device employs a Critical Conduction Mode (CRM) scheme to achieve unity power factor across a wide range of input voltages and power levels. Housed in a SOIC-8 package, the NCP1606BDR2G minimizes the number of external components required and integrates comprehensive safety protection features, making it an excellent driver for rugged PFC stages.

Key Features

  • Unity Power Factor: Achieves high power factor ratios without the need for input voltage sensing.
  • No Need for Input Voltage Sensing: Simplifies the design by eliminating the need for a line sensing network.
  • Latching PWM for Cycle by Cycle On Time Control (Voltage Mode): Ensures precise control over the on time of the driver.
  • High Precision Voltage Reference: The error amplifier reference voltage is guaranteed at 2.5 V ±1.6% over temperature ranges.
  • Very Low Startup Current Consumption: Reduces circuit consumption to less than 40 μA during the startup phase.
  • Powerful Output Driver: A -500 mA / +800 mA totem pole gate driver for rapid turn on and turn off times.
  • Programmable Overvoltage Protection (OVP): Adjustable OVP feature protects the PFC stage against excessive output overshoots.
  • Protection against Open Loop (Undervoltage Protection): Disables the PFC stage when the output voltage is excessively low.
  • Accurate and Programmable On Time Limitation: Uses an accurate current source and an external capacitor to generate the on time.

Applications

  • Electronic Light Ballasts: Ideal for lighting applications requiring power factor correction.
  • AC Adapters, TVs, Monitors: Suitable for various consumer electronics needing efficient power conversion.
  • All Offline Appliances Requiring Power Factor Correction: Applicable to any device that needs to correct power factor for efficient and compliant operation.
