Overview
The L6562ATDTR is a current-mode Power Factor Correction (PFC) controller operating in Transition Mode (TM). It features an 8-pin SOIC package and operates within a supply voltage range of 10.5V to 22.5V. The device includes a totem-pole gate driver capable of sourcing -600 mA and sinking +800 mA. It has an ultra-low start-up current of 30 µA and a low quiescent current of 2.5 mA. The internal reference voltage accuracy is 1% at 25°C.
Feature Summary
- Proprietary multiplier design for minimum Total Harmonic Distortion (THD)
- Disable function on Error Amplifier input for remote ON/OFF control
- Digital leading-edge blanking on current sense input
- Very accurate adjustable output overvoltage protection
Applications
- Constant current inverse buck LED drivers
- 400W Fixed-Off-Time controlled PFC pre-regulators
- Wide-range mains input power supplies
Procurement Notes
Verify the specific suffix 'TD' indicates tube packaging while 'TR' indicates tape and reel, as this affects handling but not electrical function. Confirm the component status is Active. Ensure the order matches the required RoHS compliance and ECOPACK2 environmental standards specified by STMicroelectronics.
Selection Notes
Select this component for designs requiring transition mode operation with high linearity. It is suitable for applications needing low standby consumption via the disable feature. Consider the 8-SOIC package constraints and the specific gate drive current capabilities when designing the MOSFET driver stage.
Part Context
This part belongs to the L6562 family, which offers improved performance over predecessors like the L6561. It utilizes BCD technology and is pin-compatible with earlier versions. The AT variant specifically denotes industrial grade performance and extended temperature range capabilities compared to standard commercial grades.
Replacement Considerations
L6562ATD is the tube-packaged equivalent with identical electrical characteristics. L6562D is a related model but carries a Not Recommended for New Design (NRND) status.
