TPS40070PWP Description

Short technical summary and product information.

The TPS40070PWP from Texas Instruments is a high-efficiency, midrange input synchronous buck controller featuring voltage feed-forward control. It operates over a wide input voltage range from 4.5V to 28V, offering design flexibility with programmable functions such as soft-start, UVLO, operating frequency, and high-side FET sensed short circuit protection.

 

This controller integrates MOSFET gate drivers for external N-channel high-side and synchronous rectifier MOSFETs. Its gate drive logic includes predictive anti-cross conduction circuitry to prevent simultaneous conduction and minimize current flow in the SR FET's body diode. The TPS40070PWP is suitable for applications including power modules, networking, telecom, PCI Express, industrial, and servers.

 

The device comes in a 16-pin PowerPAD™ package, supporting surface mount installation. It operates within an ambient temperature range of -40°C to 85°C and offers a maximum duty cycle of 93%. Key control features include current limit, enable, frequency control, power good, and soft start, with an internal 700mV reference voltage.
