The TPS40190DRCR is a high-performance synchronous step-down converter IC designed for industrial applications. It provides a highly efficient power solution for various voltage regulation requirements.
One of the key features of the TPS40190DRCR is its wide input voltage range of 4.5V to 18V, making it suitable for a variety of input sources such as batteries, adapters, and industrial power supplies. This flexibility allows it to cater to diverse application needs.
The IC incorporates a constant on-time control scheme that provides fast transient response and supports stable operation under various load conditions. This control scheme also enables seamless transition between PWM (pulse width modulation) and PFM (pulse frequency modulation) modes, ensuring high efficiency across different load ranges.
With an integrated high-side and low-side MOSFET, the TPS40190DRCR minimizes the need for additional external components, reducing the overall BOM (Bill of Materials) cost and PCB footprint. Furthermore, it eliminates the complexity of external compensation circuitry by employing a simple RC-type compensation. This simplifies the design process and enables faster time-to-market.
Additionally, the TPS40190DRCR provides excellent light-load efficiency with its pulse-skipping mode, ensuring power efficiency even in low-power consumption scenarios. It also features a programmable soft-start function, allowing designers to control the start-up behavior and avoid excessive inrush current during power-up
