The ISL81601FRZ-T7A has an integrated dual-phase buck regulator that provides up to 6A of continuous output current. It also features a maximum switching frequency of 1.2 MHz, allowing for high-efficiency operation at low power levels. Additionally, the device has adjustable peak current and frequency control, linear voltage scaling and voltage margining, undervoltage lockout, auto soft start, and output voltage tracking.

The operating principle of the ISL81601FRZ-T7A is quite simple. The controller regulates the voltage output with two high-side/low-side MOSFETs driven by a two-phase synchronous buck converter. The input voltage is first converted by the two-phase synchronous buck converter and is then used to drive the high side and low side MOSFETs (respectively). As the MOSFETs switch between on and off states, the output voltage is produced. In this way, the controller produces the desired output voltage in an efficient manner while minimizing harmonic distortion. Furthermore, the current control loop within the device enables precise control over the peak and duty cycle of each phase.
