The TPS40021PWPR from Texas Instruments is a versatile DC-DC controller designed for non-isolated synchronous buck regulator applications. It operates with an input voltage range of 2.25V to 5.5V and can provide an output voltage as low as 0.7V, with a maximum output voltage of 4V. The controller supports a programmable fixed-frequency operation from 100 kHz to 1 MHz, allowing for design flexibility and smaller component sizes.
Key features include Predictive Gate Drive technology for higher efficiency, externally adjustable soft-start, and short-circuit current limit. It also offers programmable fixed-frequency control and Power Good indication. The device supports source-only or source/sink current configurations and provides quick response to output transients.
Packaged in a 16-pin HTSSOP, the TPS40021PWPR is suitable for surface mount applications. Its operating temperature range is -40°C to 85°C (TA). This controller is well-suited for applications in networking equipment, telecom equipment, base stations, servers, and DSP power.
The TPS40021PWPR is part of the TPS4002x family, offering enhanced operation and design flexibility through user programmability. The integrated charge pump with a boost circuit provides a regulated 5V gate drive for both high-side and synchronous rectifier N-channel MOSFETs, contributing to high efficiency and a smaller, less expensive converter design.
