Overview
Description
ISL6208CBZ is a PWM controller IC from Intersil (now Renesas) used to regulate DC-DC converters for VRMs and multi-rail power supplies. It does not include MOSFETs; it drives external high/low-side MOSFETs and works with an inductor to step voltage down.
Key features
- Cycle-by-cycle, current-mode control with programmable switching frequency
- Supports synchronous rectification
- Soft-start, enable pin, and remote sense
- Overcurrent protection with current limit
- Overvoltage/undervoltage protection and power-good signaling
Packaging note
- CBZ denotes the packaging variant; check the datasheet for exact pinout and package type (commonly 8– to 16-pin).
Typical use
- CPU/GPU VRMs, telecom and embedded power supplies, and other multi-rail DC-DC designs requiring external FETs and passive components.
Tip
- Verify exact specs and pinout in the current datasheet for your specific PCB and supplier variant.
