The LNK306G-TL is an integrated power IC for switch-mode applications. It is placed in the PMIC, AC DC Converters and Offline Switchers category.

This fully integrated device is designed to control off-line powers in applications such as adapter, battery charger, and various offline switchers. It features protection features such as over current protection, current limit protection, output over voltage protection and under voltage lock-out.

The LNK306G-TL is suitable for a wide range of applications due to its flexibility and ease of use. It can be used as a replacement to linear or Discrete regulators and is designed to minimize external components needed. The device can provide and regulate a range output voltage of up to 24V, allowing for a wide range of power supply requirements.

The working principle of the LNK306G-TL is based on the use of a Pulse Width Modulation (PWM) and a Low Dropout Regulator (LDO) control system. It includes a high voltage Pulse Width Modulation (PWM) controller and a high voltage low power consumption 500mA FET driver. This allows for both high efficiency and maximum load current.

The PWM control block functiones as a switching feed back control which uses a comparator to compare the output voltage and the reference voltage. It controls the output power by switching on and off the FET driver. It also provides protection features such as under voltage protection, over current protection and output over voltage protection.

The low dropout regulator (LDO) uses an active low pass filter which is used to filter out the switching noise and inductive kickback. The output power is determined by a voltage sense resistor which monitors the output voltage and provides an input to the comparator of the PWM control block.

The combination of the PWM and LDO control blocks allows the device to provide high efficiency with a low ripple voltage and low harmonic generation. The protection features make it suitable for use in a wide range of applications from adapters and battery chargers to offline switchers.

The LNK306G-TL is a fully integrated power IC for off-line applications. It offers high levels of power efficiency and protection features with low external components required. The two control blocks provide the device with flexibility for a wide range of applications. Its ease of use, along with its low power consumption, makes the device an ideal choice for a variety of applications from AC-DC converters and offline switchers to adapters and battery chargers.
