Key Features & Applications
- 3 V to 28 V input range hysteretic synchronous step-down controller — works with external MOSFETs for scalable output current
- Hysteretic control topology delivers ultra-fast transient response without compensation network design complexity
- Integrated high-side and low-side MOSFET gate drivers with adaptive dead-time control for high-efficiency power conversion
- Wide 3–28 V input supports 5 V, 12 V and 24 V bus architectures in industrial, server and telecom applications
- Comprehensive protection suite: cycle-by-cycle over-current, output OVP, UVLO and thermal shutdown
- Small 3×3 mm QFN with exposed pad for thermal performance in space-constrained high-current DC-DC designs
