PT4213
Primary Side CC Controller
GENERAL DESCRIPTION
The PT4213 is a primary side regulated constant
current controller, which is designed for LED lighting
applications. The device is optimized for high
performance and cost-effective applications. With
Powtech’s proprietary constant current compensation
technique accurate constant current regulation is
achieved without the need of a secondary feedback
circuitry. Integrated primary inductance compensation
circuitry provides accurate constant current operation
despite variations in primary inductance. Excellent EMI
performance is achieved with frequency jittering
function together with soft driving control at totem pole
gate drive output.
The device also features a complete set of protection
functions to protect against all fault conditions
including output open/short circuit, line under-voltage,
and over temperature.
The PT4213 is available in an SOT23-6 package.
FEATURES
z CC without secondary feedback
z Inductance compensation
z Low startup current (<10uA)
z Adjustable primary side current limit
z VCC/FB over voltage protection
z VCC/FB UVLO
z Feedback loop open circuit protection
z Over temperature protection
z RoHS compliant
APPLICATIONS
z Off-line High Brightness General LED Lighting
z Integrated LED Lamps such as GU10, E27,
PAR20/20/38 LED Lamps

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Recommended
Operating Range indicates conditions for which the device is functional, but do not guarantee specific performance
limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which
guarantee specific performance limits. This assumes that the device is within the Operating Range. Specifications are
not guaranteed for parameters where no limit is given, however, the typical value is a good indication of device
performance.
