ADI ADP2116多功能同步DC电源转换方案
ADI 公司的ADP2116是多功能同步降压DC/DC开关稳压电源,两个PWM通路可提供独立的3A和3A或3A和2A输出或配置成单路6A输出.输入电压2.75V-5.5V,可选择固定输出电压0.8 V, 1.2 V, 1.5 V, 1.8 V, 2.5 V或 3.3 V,或可调节输出电压低至0.6V,效率高达95%.主要应用在点负载,通信和网络系统消费类电子,工业和仪表与医疗设备.本文介绍ADP2116主要特性,方框图,几种典型应用电路和ADP2116评估板的主要特性,电路图和所用材料清单.
The ADP2116 is a versatile, synchronous, step-down switching regulator that satisfies a wide range of customer point-of-load requirements. The two PWM channels can be configured to deliver independent outputs at 3 A and 3 A (or at 3 A and 2 A) or can be configured as a single interleaved output capable of delivering 6 A. The two PWM channels are 180° phase shifted to reduce input ripple current and input capacitance.
The ADP2116 provides high efficiency and can operate at switching frequencies of up to 2 MHz. At light loads, the ADP2116 can be set to operate in pulse skip mode for higher efficiency or in forced PWM mode for noise sensitive applications.
