A81805中文资料40 V, 2.5 A, Synchronous Buck Regulator with Low EMI and 6 µA Quiescent Current数据手册Allegro规格书

描述 Description

The A81805 is a powerful synchronous buck regulator that offers high efficiency over the full load of up to 2.5A. This regulator's unique architecture reduces the amount of EMI generated by the switching components to minimize the number of external components. The A81805 has a very low 6uA quiescent current which will help maximize battery life in standby mode. The input voltage range is wide enough to survive many transients in automotive and industrial applications and not turn off when the voltage drops.

特性 Features

• Wide input voltage range: 3.5V to 40V
• AEC-Q100 Grade 0 qualified
• High efficiency: 92%, 12 to 5V at 1A
• Low EMI: spread spectrum dithering
• Wide switching frequency range: 250kHz to 2.5MHz
• Up to 2.5A continuous output current
Typical Applications:
• Infotainment
• Battery-Powered Systems
• Industrial Systems
• Container Tracking
• Handheld Instruments
• Audio Systems
• ADAS
• Instrument clusters
• Power Steering
• Radar

简介

A81805属于集成电路（IC）的稳压器-DC-DC开关稳压器。由制造生产的A81805稳压器 - DC-DC 开关稳压器DC-DC 开关稳压器 PMIC（电源管理集成电路）产品族中的产品是元器件级设备，用于需要稳定 DC 输入电压和/或将其转换为不同幅度的输出电压的应用。这些器件与称为“控制器”PMIC 的类似产品的区别在于集成了主开关元件，设备提供的电力会通过该元件。
