TPS40070PWPR Description

Short technical summary and product information.

The TPS40070PWPR from Texas Instruments is a high-efficiency, midrange input synchronous buck controller with voltage feed-forward control. It is designed for step-down conversion and operates over a wide input voltage range of 4.5V to 28V.

 

This controller features a programmable fixed-frequency operation up to 1MHz, a voltage-mode controller, and predictive gate drive with anti-cross conduction circuitry. It includes internal gate drive outputs for high-side and synchronous N-channel MOSFETs. The device also offers features such as soft-start, UVLO, and programmable high-side sense short circuit protection.

 

Packaged in a 16-pin HTSSOP, the TPS40070PWPR is suitable for applications including power modules, networking, telecom, PCI Express, industrial, and servers. Its robust design and flexible programmability make it a versatile choice for power supply designs requiring efficient voltage regulation.

 

Key electrical characteristics include a 4.5V to 28V input voltage range, a maximum output duty cycle of 93%, and an internal 700mV reference voltage. The operating temperature range is -40°C to 85°C.
