LNK3206GQTL Image

The LNK3206GQTL from Power Integrations is an Automotive Qualified Power Switch IC that is designed to provide a significant reduction in component count compared to traditional discrete solutions, thereby making it a highly reliable device. It requires an input voltage of 30 - 550 V. This power switch IC consists of a 750 V power MOSFET, oscillator, On/Off control, a high-voltage switched current source for self-biasing, current limit comparator, capacitors, and inductors. It supports buck, buck-boost, and flyback topologies and provides excellent load and line regulation. The power switch IC has a frequency jittering function to reduce the complexity of the EMI filter and integrates pin-out to allow simplification of PCB heat sink operation.

The LNK3206GQTL is incorporated into this IC maintains constant efficiency over a wide input voltage range and is designed to easily meet all global energy efficiency regulations. This AEC-Q100-qualified switch is equipped with output over-voltage protection (OVP), hysteretic over-temperature protection (OTP), and an auto-restart circuit to protect the device and systems from lost regulation and short-circuit-related damages. It is available in a surface-mount package that measures 9.05 x 9.45 mm and is ideal for emergency power supply for traction inverters and auxiliary power supplies for automotive HVAC, climate control, DCDC converter, and onboard charging applications.
