The TPS51285A and TPS51285B are cost-effective, dual synchronous buck controllers designed for notebook and embedded power systems. They integrate 5V and 3.3V LDOs, delivering stable outputs with adaptive on-time D-CAP™ mode control for fast load response.
These controllers feature auto-skip and ULQ™ modes for reduced standby power and extended battery life. With internal soft-start, low-side RDS(on) current sensing, built-in output discharge, and comprehensive protections (OVP, UVP, OCP), they ensure efficient and safe operation.
