3BR1565 datasheet pinout

Description

3BR1565 is a CoolSET-F3R FullPak off-line SMPS controller featuring a 650V avalanche-rugged CoolMOS power stage with a built-in startup cell and a wide VCC range up to 25V using BiCMOS technology. It integrates Active Burst Mode for standby power below 100mW at no load and Vin = 270VAC, along with fast load-jump response, 67kHz fixed switching frequency, built-in soft start, and comprehensive Auto Restart protection. The device targets off-line adapters and higher-power SMPS applications such as DVD R/W, DVD combi systems, set-top boxes, and other compact power supply designs, with the ICE3BR1565JF version specified with 1.5Ω RDS(on) and maximum output power of 68W/125W.

The CoolSET-F3R FullPak is the enhanced version of CoolSET-F3 and targets for the Off-Line Adapters and high power range SMPS in DVD R/W, DVD Combi, set top box, etc. It has a wide Vcc range to 25V by adopting the BiCMOS technology. With the merit of Active Burst Mode, it can achieve the lowest Standby Power Requirements (<100mW) at no load and Vin = 270VAC.

Features

  • 650V avalanche-rugged CoolMOS with built-in startup cell
  • Active Burst Mode for lowest standby power
  • Standby power below 100mW at no load and Vin = 270VAC
  • Fast load-jump response in Active Burst Mode
  • 67kHz internally fixed switching frequency
  • Wide VCC range up to 25V
  • BiCMOS technology
  • Auto Restart Protection Mode for overload, open-loop, VCC undervoltage, overtemperature, and overvoltage
  • Built-in soft start
  • Built-in blanking window with extendable function
  • RDS(on) of 1.5Ω for ICE3BR1565JF
  • Maximum output power of 68W/125W

Working Principle

  • The CoolSET-F3R combines a high-voltage 650V CoolMOS power device with the controller and built-in startup cell for off-line switching power supply operation.
  • The integrated startup cell provides the initial startup function and reduces the need for additional high-voltage startup circuitry.
  • Active Burst Mode reduces switching activity under light-load conditions to achieve very low standby power consumption.
  • The controller remains capable of responding quickly to a sudden increase in load while operating in Active Burst Mode.
  • The internally fixed 67kHz switching frequency provides a defined operating frequency for the SMPS power stage.
  • Built-in soft start controls the initial startup sequence and helps reduce excessive electrical stress during power-up.
  • The blanking window prevents short-duration switching events from unnecessarily activating the protection function and can be extended when required.
  • Auto Restart Protection Mode provides protection against overload, open-loop operation, VCC undervoltage, overtemperature, and overvoltage conditions.

P out max = 68W / 125W 

How to Choose This Part

  • Choose 3BR1565 when an off-line adapter or higher-power SMPS requires an integrated 650V CoolMOS power stage and controller.
  • It is suitable for applications where standby power below 100mW is required at no load and Vin = 270VAC.
  • The integrated startup cell is useful when minimizing the external component count on the high-voltage primary side.
  • The 67kHz internally fixed switching frequency provides a defined operating point for transformer and EMI design.
  • Consider the 1.5Ω RDS(on) specification of ICE3BR1565JF when evaluating efficiency, conduction loss, and thermal requirements.
  • For higher-power SMPS applications, the stated 68W/125W output power range should be evaluated against the actual converter topology, thermal conditions, and operating environment.

Applications

  • Off-line adapters
  • High-power SMPS
  • DVD R/W power supplies
  • DVD combi power supplies
  • Set-top box power supplies
  • Compact off-line switching power supplies
  • Low-standby-power AC-DC converters
