TPS40009DGQ TI PWM Controller | 10-HVSSOP | 4.5V-15V Input, 1MHz

Product Overview

The TPS40009DGQ from Texas Instruments is a high-performance, low-input voltage synchronous buck controller designed for point-of-load (POL) regulation in distributed power systems. It operates from a 4.5V to 15V input supply and provides a regulated output voltage as low as 0.7V with ±1% accuracy. The device features a fixed-frequency voltage-mode control architecture with a programmable switching frequency up to 1 MHz, enabling small external components and fast transient response. Housed in a compact 10-pin HVSSOP package, the TPS40009DGQ integrates key functions such as soft-start, undervoltage lockout (UVLO), and overcurrent protection, making it ideal for space-constrained applications requiring high efficiency and reliability.
