TPS54429EPWPR Description

Short technical summary and product information.

The TPS54429EPWPR from Texas Instruments is an adaptive on-time D-CAP2 mode synchronous buck converter. This device is designed for cost-effective, low component count power bus regulation in various end equipment.

 

Key electrical specifications include a wide input voltage range of 7V to 18V and an adjustable output voltage range from 0.76V to 5.5V. It can deliver up to 4.5A of current and operates at a switching frequency of 700kHz. The integrated FETs have low on-resistance, with the high side at 63 mΩ and the low side at 55 mΩ. It also features high efficiency, consuming less than 10 μA at shutdown.

 

The converter utilizes D-CAP2 mode control for fast transient response without external compensation components. It supports seamless transition between PWM mode and Eco-mode for high efficiency at light loads. The device is optimized for lower duty cycle applications and can adapt to various output capacitors, including ultra-low ESR ceramic capacitors.

 

Packaged in a 14-pin HTSSOP, the TPS54429EPWPR is designed for surface mounting and operates within an ambient temperature range of -20°C to 85°C. Applications include power supplies for digital TVs, Blu-ray players, networking home terminals, and digital set-top boxes.
