The LV2862 is a PWM DC/DC buck (step-down) regulator. With a wide input range from 4 V to 60 V, the device is designed for a wide range of applications, from industrial to automotive, for power conditioning from unregulated source. An ultra-low 1-µA shutdown current can further prolong battery life. Operating frequency is fixed at 770 kHz (X version) and 2.1 MHz (Y version), allowing the use of small external components while still being able to have low output ripple voltage. Soft start and compensation circuits are implemented internally, which allows the device to be used with minimized external components.

The LV2862 is optimized for up to 600-mA load currents. The device has a 0.765-V nominal feedback voltage.

The device has built-in protection features such as pulse-by-pulse current limit, thermal sensing, and shutdown due to excessive power dissipation. The LV2862 is available in a low profile SOT-6L package.

參考設計

PMP23454 — 通用輸入、430W 電動工具充電器參考設計

此參考設計為適合電動工具應用的通用輸入、430W 定電流 (CC)、定電壓 (CV) 充電器。此參考設計在涓流充電模式下支援 0V 至 12.5V 的輸出電壓範圍,在全充電模式下支援 7.5V 至 22.5V 的輸出電壓範圍。已停用功率因數校正 (PFC),且在涓流充電模式下,電感器-電感器電容器 (LLC) 會進入低功率模式,因此在 115Vac 時可達到 174mW 的無負載待機功率,在 230Vac 時則可達到 325mW。此參考設計使用 UCC28180、UCC256604、UCC24612、TL331 和 TPS7B8133 裝置。
