The Texas Instruments LM27403SQX/NOPB is a voltage-mode synchronous buck controller designed for efficient power management. It features a wide input voltage range of 3V to 20V and can deliver output voltages from 0.6V to 19V, with a maximum output current of 30A.
Key electrical specifications include a maximum duty cycle of 93%, a switching frequency range of 200kHz to 1.2MHz, and a typical quiescent current of 3.5mA. The controller supports features such as Enable, Frequency Control, Power Good, Soft Start, and Tracking. It also includes a 0.6V reference with 1% feedback accuracy and a minimum on-time of 30ns for low output voltages.
This device is housed in a 24-WQFN (4x4) package and utilizes surface mount technology. The operating temperature range is -40°C to 125°C (TJ). Its synchronous rectification capability contributes to high efficiency, with reported efficiencies up to 97%.
