Intersil ISL6228 datasheet supplied as an 875 KB PDF. The ISL6228 is a dual-channel synchronous buck PWM controller designed for notebook power, often generating system or chipset rails on laptop motherboards. The document covers pin descriptions, enable and power good behaviour, soft-start, overcurrent protection and an application circuit. Technicians consult it to verify enable inputs, supply voltage and feedback on each channel when a rail is missing, and to locate the gate drive and phase pins of the external MOSFETs during fault finding.
