TNY266P

The TNY266P is a PWM (pulse-width modulation) control integrated circuit (IC) which is typically used in power conversion applications. In particular, it can be used in applications such as AC-DC converters, offline switchers, switch mode power supplies, power factor correction circuits, and motor control systems.

The TNY266P is a PWM controller designed for high-efficiency, low-power applications. It is capable of producing a regulated voltage from either an AC or DC input, and can accept input voltages from 8V to 20V. In addition, it can output up to 600mA of current from a output voltage up to 20V. The TNY266P also features a high-side current limit and a programmable soft-start for enhanced system-level performance.

The TNY266P is a versatile device and can be used to design a wide variety of power conversion systems. In applications such as AC-DC converters and offline switchers, the IC can be used in conjunction with an external MOSFET to create a full-bridge power converter. The IC also includes protection features such as over-temperature, over-current and under-voltage lockout functions which help to ensure safety and reliability as well as improve system efficiency.

In terms of its working principle, the TNY266P integrates a current mode PWM controller and a high-side MOSFET driver into a single package. The IC controls the on-time of the external MOSFET based on an input voltage signal, and changes the duty cycle of the PWM signal in order to adjust the output voltage. The IC also regulates the output current based on an externally supplied reference voltage. The output voltage is monitored and regulated through an internal error amplifier, and a feedback signal is fed back to the PWM comparator to ensure the correct analog voltage value is achieved at the output.

Additionally, the TNY266P also utilizes a variety of features to help improve the efficiency and reliability of the system. This includes a proprietary current-mode control architecture, which helps minimize switching losses and reduce the stress on the external MOSFET. The device also includes under-voltage lockout, over-temperature, and over-current shutdown circuits, allowing for safe and reliable operation. The IC also features an adjustable soft-start and an adjustable frequency oscillator, helping to reduce the stress on system components during the start-up phase.

Overall, the TNY266P is a versatile IC which can be used in a variety of power conversion applications, such as AC-DC converters and offline switchers. With its integrated PWM controller and MOSFET driver, the IC is ideal for building efficient, reliable, and high-performance power conversion systems.
