INN3166C-H110-TL is an advanced power management integrated circuit (PMIC) with AC/DC converters, offline switchers, offering an ideal power solution for audio applications. It is designed to provide high-efficiency, high-reliability and low-noise operation in a small form factor.

The INN3166C-H110-TL is a single-channel, AC-DC offline switcher IC with a low-power, cost-effective and ultra-small footprint design. It supports a wide input voltage range (16VAC to 28VAC) and provides a robust output voltage ranging from 5V to 24V. The device features high-voltage start-up, low startup current, low standby power, fixed frequency switch mode operation and low-noise operation.

The innovative power supply design of the INN3166C-H110-TL employs a transformerless, bridge rectified, step-down topology in order to achieve high power efficiency. The IC also contains multiple built-in protection features such as over-temperature protection, under-voltage lockout and over-current protection.

The INN3166C-H110-TL is suitable for various applications such as audio power amplifiers, PC power supplies, home automation, smart home, communication systems, and media player. The IC enables the power system design to be further miniaturized and most importantly, the low quiescent current operation of this device consumes a minimum amount of standby power.

The INN3166C-H110-TL works in a two-stage conversion mode. In the first stage, the integrated AC/DC converter converts the AC input to a DC output. In the second stage, the integrated offline switcher transforms the DC input to a regulated output voltage.

The internal power switches of the INN3166C-H110-TL employ a fixed frequency, current-mode, pulse-width modulation (PWM) control technique to achieve a high level of performance. The output voltage is regulated by an inner-current compensating loop and the output voltage feedback pin. The frequency can be set via an external resistor, allowing the user to tailor the operating frequency to the application.

The INN3166C-H110-TL also features a wide range of protection features. The device has built-in under-voltage protection, over-current protection, over-voltage protection, and over-temperature protection, which provide the highest level of safety for the system.

In summary, the INN3166C-H110-TL is a high-efficiency and low-power single-channel PMIC with AC/DC converters, offline switchers, and various built-in protection features. It is an ideal power solution for audio applications, providing high reliability and low noise operation in a small form factor.
