ICE2B165FKLA1 Application Field and Working Principle

PMIC (Power Management IC) is an important component of embedded systems in the market, playing a key role in power management. It is used to provide power from a variety of sources (AC, DC, battery, etc.) to the device or system components. Different types of PMICs are used in different applications. This article will discuss the application fields of ICE2B165FKLA1, which is classified as an AC/DC converter, offline switch, and the working principle behind this PMIC.ICE2B165FKLA1 is a single-channel flyback PWM (pulse-width modulation) controller which can be used as an AC-DC converter, an offline switch, and a low-power offline switching power supply. This PMIC can be used to provide fixed output power in applications such as lighting, adapter, and charger applications. In addition, this offline switch can also provide constant voltage regulation with a maximum output power of 33W.The working principle behind ICE2B165FKLA1 is straightforward. This PMIC features a high-performance power management IC that provides pre-regulation, over-current protection, over-voltage protection, and fixed output power. The IC also incudes a Pulse-Width Modulator (PWM) which provides output with fixed frequency regulation and variable-speed control. The external components are used to sense the output voltage/current, provide input voltage/current, and handle the interleaving switching.When the AC input voltage is detected, firstly, the PMIC operates in DCM (Continuous Conduction Mode) to stabilize the output voltage, followed by an interleaving PWM operation to generate the desired output power. The PWM controller senses the output voltages/currents and regulates the applied power by adjusting the duty cycle of the pulse width modulation. This ensures that the power is limited within the range specified by the application. The ICE2B165FKLA1 can provide a wide range of protections, such as over-voltage, over-current, over-temperature and overload protection. The overload protection threshold can be adjusted for different applications. The PMIC also includes a power-on reset circuit and an under-voltage lockout circuit to ensure reliable operations in any environment.To conclude, ICE2B165FKLA1 is a single-channel flyback PWM controller suitable for AC/DC converter, offline switch, and low-power offline switching power supply applications. This PMIC features a high-performance power management IC that provides pre-regulation, over-current protection, over-voltage protection, and constant voltage regulation with a maximum output power of 33W. The operating principle of ICE2B165FKLA1 is based on the PWM controller which senses the output voltages/currents and regulates the applied power by adjusting the duty cycle of the pulse width modulation. The ICE2B165FKLA1 also features various protections, such as over-voltage, over-current, over-temperature, overload protection and power-on reset and under-voltage lockout circuits.
