The ISL6291-2CRZ is a three-phase synchronous buck controller with integrated high-sidegate drivers and gate drivers for N-channel MOSFETs. It is manufactured by Renesas Electronics Corporation. The device is highly efficient, with a switching frequency of 2.5MHz, and is capable of driving up to 3.2V output voltage. The ISL6291-2CRZ also includes various protection features such as over-voltage protection, over-temperature protection, undervoltage lockout, over-current protection, and a programmable soft-start feature. It is suitable for low-power, low-voltage applications such as notebook computers, digital cameras, and portable media players.
