Tps54329ddar soic-8 switching regulator Ti

describe

Tps54329 is an adaptive real-time d-cap2 ™ Mode Synchronous Buck converter. Tps54329 enables system designers to complete a set of power bus voltage regulators for various terminal equipment, which has the solution of economy, low number of components and low standby current. The main control loop of tps54329 uses d-cap2 ™ Mode control, providing * * transient response without external compensation components.

The tps54329 also has a proprietary circuit that enables the device to use low equivalent series resistance (ESR) output capacitors, such as poscap or sp-cap, and * low ESR ceramic capacitors. The device operates under 4.5-v to 18-v VIN input. The output voltage can be programmed between 0.76 V and 7 v. The device also has adjustable soft start time. Tps54329 is packaged in 8-pin DDA and can work at - 40 ° C to 85 ° C.
