The LM25141-Q1 is a synchronous buck controller from Texas Instruments, designed for high-voltage, wide-VIN, step-down regulator applications. It operates with an input voltage range of 3.8 V to 42 V and supports adjustable output voltages from 1.5 V to 15 V with ±0.8% accuracy.
This controller features a fixed switching frequency of 2.2 MHz or 440 kHz, with ±5% accuracy. It includes features such as slew rate control for simplified EMI compliance, optional spread spectrum, and synchronization to an external clock. The device meets CISPR 25 / EN 55025 EMI standards.
Key electrical specifications include a 75-mV current limit threshold with ±0.9% accuracy, a shutdown mode quiescent current of 10 µA typical, and a low standby mode quiescent current of 35 µA typical. The device is AEC-Q100 qualified for automotive applications, with a temperature grade of 1 (-40°C to +125°C ambient operating temperature).
The LM25141-Q1 is available in a 24-VQFN (4x4 mm) package with wettable flanks, suitable for surface mounting. Its applications include automotive systems such as infotainment, instrumentation clusters, and advanced driver assistance systems (ADAS).
