Descriptions:

The ISL6522CBZ is a high-performance dual synchronous buck PWM controller designed for generating regulated output voltages in power supply applications. It integrates two independent PWM controllers, allowing it to drive two separate power stages. The device is optimized for high efficiency and precise voltage regulation, making it suitable for applications such as DC-DC converters, point-of-load (POL) regulators, and embedded power supplies.

Features:

• Dual synchronous buck PWM controllers in a single package
• Adjustable output voltage via external feedback resistors
• Precision voltage reference (±1% accuracy)
• Integrated high-current MOSFET drivers
• Programmable soft-start for controlled power-up
• Overvoltage (OVP), undervoltage (UVP), and overcurrent (OCP) protection
• Adjustable switching frequency (up to 1MHz)
• Low-power shutdown mode
• Thermal shutdown protection
