PMIC - AC DC Converters, Offline Switchers
Introduction
ICE3A5065PBKSA1 is a highly integrated off-line SMPS (Switch Mode Power Supply) primary control IC with built-in 700V power MOSFET. It is ideal for low power (<100W) AC/DC converter designs. This IC integrates a voltage mode primary control with an active loop compensation to reduce the amount of external components needed to design a power converter.
Application Field
ICE3A5065PBKSA1 can be used in various applications like a desktop computers, notebooks, TV, monitors, printers, etc. Moreover, the high integration and minimal external components count make this IC optimal choice for low power AC/DC converters up to 100W.
Working Principle
The IC implements a primary control loop in order to keep the switching frequency stable. It has an under voltage lock-out (UVLO) to protect the system from in-rush current and low voltage. Moreover it can detect the overload condition and trigger the over-current protection (OCP) circuit immediately.
The ICE3A5065PBKSA1 allows to run at various frequencies: it can be selected between 10kHz, 20kHz and 30kHz. This makes the IC suitable for the design of universal AC/DC power adapters.
The IC integrates a low side driver which controls the ON/OFF state of the power MOSFET and sense the voltage across the power MOSFET. It also embeds a reset signal for the secondary loop control.
The ICE3A5065PBKSA1 implements a power MOSFET gate drive signal for the primary side switching. It is possible to adjust the maximum gate voltage to reduce the switching loss.
The internal Feedback voltage regulator of the IC provides the stable output voltage regulation with no line-load regulation variation. It can regulate the output voltage within a range of 14 V to 61 V.
By combining a Pulse Width Modulation (PWM) signal, a VCC supply, a HV_Power connected to the power MOSFET and a Feedback voltage connected to the output inductor of the converter, the IC is able to implement a Voltage Feed Forward Mode compensator to control the output voltage of the converter.
The IC provides a Thermal Shutdown (TSD) to protect the IC from over temperatures. It also integrated a Thermal loop to allow the control of the power MOSFET power dissipation. The over-temperature protection (OTP) will inhibit the switching circuit if the MOSFET temperature is greater than the 125°C.
Conclusion
The ICE3A5065PBKSA1 is an ideal choice for designs of low power (<100W) AC/DC converters. It implements primary control loop with an active loop compensation to reduce the amount of external components needed to design a power converter, and is able to run at various frequencies. It also integrates an under voltage lock-out (UVLO) to protect the system from in-rush current and low voltage, a reset signal for the secondary loop control, a low side driver which controls the ON/OFF state of the power MOSFET, and a Feedback voltage regulator to provide stable output voltage regulation. Additionally, it embeds a thermal shutdown (TSD) and an over-temperature protection (OTP) to protect the IC from over temperatures.
