Power management integrated circuits (PMICs) are specialized chip solutions that manage the power conversion in a system. The ISL6146AFRZ-TK is an ultra-low ESR dual-channel buck regulator IC (R-DCSB) from Intersil with high efficiency over a wide range of load conditions. It features an integrated OR-controller, ideal diode, controllerless ideal diode, and a high-side MOSFET, giving it the ability to accurately monitor two channels of dc power in a small form factor.The ISL6146AFRZ-TK offers low-ESR, dual-channel buck regulation that uses a synchronous rectifier topology, providing a high level of efficiency with minimal noise and power dissipated in the external components. It has a wide input voltage range from 2.3 V to 4.5 V and can output a fixed voltage and current up to 4.4 A. The wide range of output currents makes it suitable for various applications like FPGAs, microprocessors, DSPs, and power conversion stages. It has built-in features such as programmable dynamic voltage scaling, soft start, and adjustable switching frequency and current limit.The OR-controller in the ISL6146AFRZ-TK senses a difference in output voltage between two channels and combines the channels to obtain a common output voltage. This feature helps to reduce output voltage ripples, which could otherwise lead to instability in the system. The integrated ideal diode in the IC is used to eliminate the need for external diodes in parallel with the output MOSFETs, reducing board space and improving efficiency. The controllerless ideal diode works by controlling the current flow from one of the channels automatically switching it off when the other channel is supplying power. This reduces power dissipation in power conversion stages.The ISL6146AFRZ-TK also has an integrated high-side MOSFET which helps in clearing the output channel capacitors when the system is powered down. This removes residual charge in the capacitors and prevents the system from behaving erratically during the power up phase. It also reduces the size of the board, since additional components aren’t needed for this purpose.In summary, the ISL6146AFRZ-TK is a highly integrated power management IC with an OR-controller, ideal diode, controllerless ideal diode, and a high-side MOSFET. It offers efficiencies of up to 95%, making it suitable for a range of applications. The low-ESR power stage design helps to reduce noise and power waste. The integrated high-side MOSFET eliminates the need for external components, reducing board space and power consumption.
