TPS54328DDA Description

Short technical summary and product information.

The TPS54328DDA from Texas Instruments is an adaptive on-time D-CAP2 mode synchronous buck converter. It is designed for cost-effective, low component count, and low standby current solutions for various end-equipment power bus regulators.

 

Key electrical specifications include an input voltage range of 4.5V to 18V and an output current capability of up to 3A. The output voltage is adjustable from 0.76V to 7.0V. The device features a switching frequency of 700kHz and integrated FETs with low on-resistance (100 mΩ high-side, 70 mΩ low-side).

 

The D-CAP2 mode enables fast transient response without external compensation components. The adaptive on-time control supports seamless transition between PWM mode at higher loads and Eco-mode at lighter loads, maintaining high efficiency. The converter is optimized for lower duty cycle applications and supports ceramic output capacitors.

 

Packaged in an 8-SO PowerPad surface mount package, the TPS54328DDA operates within a temperature range of -40°C to 85°C. Its features make it suitable for a wide range of low voltage system applications.
