PMIC - AC DC converters, offline switchers, are used to convert AC into DC power and regulate any undesirable voltage fluctuations for a given output voltage. The ICE3BR4765JFKLA1 is a 2-channel offline switcher with switched-mode power supply protection, soft start, and current limiting features. It features two high-frequency Power MOS drivers, an output voltage of up to 96V, and a maximum output current of 2.5A.

Device Overview

The ICE3BR4765JFKLA1 is a bi-directional (AC to DC and DC to AC) voltage regulator chip used for offline power conversion applications. It is designed for use with high-frequency buck converters and works to provide surge protection, load regulation, and over-voltage protection for a wide variety of output voltages. The device is housed in the 16-pin DIP (dual in-line package) that measures 5.08mm x 7.62mm x 2.54mm. It features an integrated driver MOSFET metal-oxide-semiconductor field-effect transistor (MOSFET). A metal-oxide-semiconductor field-effect transistor is a transistor which is used to amplify signals in electronic circuits.

The device has an adjustable threshold voltage of up to 96V, with the default being 80V. It also features a maximum output current of 2.5A, with the default being 0.85A. The device provides protection against over-current, over-voltage, and over-temperature conditions. It also features a wide input voltage range (5V – 900V AC/DC), soft start, and a wide range of operating temperatures.

Working Principle

The working principle behind the ICE3BR4765JFKLA1 is relatively simple. The device consists of an integrated driver MOSFET and a power supply voltage regulator. The input voltage is first stepped down from AC to DC voltages through a bridge rectifier. The output of the rectifier is then sent to a power supply voltage regulator, which is used to regulate any fluctuations in the voltage for a given output voltage.

The power supply voltage regulator is connected to the integrated driver MOSFET which acts as a switch to control the switching of power between AC and DC voltages. The voltage regulator is also used to provide surge protection, over-voltage protection, and current limiting features. When the MOSFET is on, the output voltage is AC, while when it is off, the voltage is DC.

Applications

The ICE3BR4765JFKLA1 has a wide range of applications, including in industrial equipment and controls, automotive accessories and components, home appliances, computer peripherals, lighting controls and more. It can be used for applications such as motor controllers, lighting fixtures, power supplies, power converters, and more. Additionally, the device can be used for a variety of input voltages from 5V to 900V AC/DC.

The ICE3BR4765JFKLA1 is also suitable for use in high-frequency buck converters, as it provides load regulation, surge protection, and over-voltage protection for a wide variety of output voltages. Due to its wide input voltage range and adjustable output current, the device is well-suited for many AC/DC power applications, such as motor control, industrial equipment, and home appliance applications.
