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