TPS54326

illustrate

The TPS54326 is a D-CAP2™ mode synchronous buck converter with adaptive turn-on time. This TPS54326 enables system designers to complete a regulated power bus kit for a wide range of end devices with a cost-effective, low-component-count, low-standby current solution. D-CAP2™ mode control for TPS54326 main control cycle provides a fast transient response without the need for external components. Time control for adoption is controlled in high efficiency, supporting seamless and reduced frequency eco-mode operation in light load conditions under heavy load conditions, and PWM mode operation between frequency.

The TPS54326 also features dedicated circuitry that allows the device to accommodate output capacitors with two low equivalent series resistors (ESRs), such as POSCAP or SP-CAP ceramic capacitors with ultra-low ESR.
