Introduction

AI Translation

TX4140 is a high-voltage input synchronous buck regulator. The TX4140 operates over a wide input voltage range, delivering 2.4A continuous output current with excellent load and line regulation performance. The switching frequency is fixed at 130kHz, and the synchronous architecture enables high-efficiency designs. Current-mode operation provides fast transient response and simplifies loop compensation. The TX4140 requires a minimal number of off-the-shelf standard external components. Additional features include cable compensation, hiccup current protection, and thermal shutdown. The TX4140 converter is available in an industry-standard SOP-8L package.
