LV2862数据手册集成电路（IC）的DCDC开关稳压器规格书PDF

描述 Description

The LV2862 is a PWM DC/DC buck (step-down) regulator. With a wide input range from 4 V to 60 V, it is suitable 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. It 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 (2.9 mm × 1.6 mm × 0.85 mm).
