The TPS54327 is a D-CAP2 mode synchronous buck converter with adaptive on-time. TheTPS54327 enables system designers to complete a cost-effective, low component count, low standby current solution for a regulated power bus kit for a wide range of end devices. Provides fast, transient response without external compensation components for D-CAP2 mode control cycling of the TPS54327 main control. The TPS54327 also features dedicated circuitry that enables devices to adopt low equivalent series resistance (ESR) output capacitors, such as POSCAP or SP-CAP ceramic capacitors, and ultra-low ESR. The device operates from an 18-V VIN input to 4.5 - V. The output voltage can be set to 0.
