Working Principle of ZXRD1033PQ16TA

The ZXRD1033PQ16TA implements a synchronous buck DC DC conversion technique. The device manages 3-phase synchronous buck conversion, with two feedback channels. A high current MOSFET is placed at the output stage, to ensure correct voltage regulation as well as efficiency. The maximum output current is set to 90A.

The device operates according to the following cycle. When the enable pin is set to high, the user powers up the circuit. This activates the internal bias regulator and the internal high side gate driver. The internal PLL then produces a sinusoidal wave, which is applied to the gate of the MOSFETs. This creates a continual current flow, which is regulated to maintain output voltage stability. The device then senses the current load and adjusts the output voltage accordingly.

The ZXRD1033PQ16TA also features adjustable power saving modes, adjustable current limit, and adjustable over-voltage protection. Additionally, it offers a soft start feature, allowing for smooth operation within a wide range of load conditions. Finally, the device also has an adjustable slew rate to ensure optimum efficiency.
