The TPS54329 is an adaptive on-time D-CAP2 mode synchronous buck converter. TheTPS54329 enables system designers to complete the suite of various end equipment’s power bus regulators with a cost effective, low component count, low standby current solution. The main control loop for the TPS54329 uses the D-CAP2 mode control which provides a fast transient response with no external compensation components. The TPS54329 also has a proprietary circuit that enables the device to adopt to both low equivalent series resistance (ESR) output capacitors, such as POSCAP or SP-CAP, and ultra-low ESR ceramic capacitors. The device operates from 4.5-V to 18-V VIN input. The output voltage can be programmed between 0.76 V and 7 V. The device also features an adjustable soft start time. The TPS54329 is available in the 8-pin DDA package, and designed to operate from –40°C to 85°C.
