ADP2106ACPZ-1.2-R7集成电路（IC）的稳压器-DC-DC开关稳压器规格书PDF中文资料

ADP2106ACPZ-1.2-R7属于集成电路（IC）的稳压器-DC-DC开关稳压器。由亚德诺半导体技术有限公司制造生产的ADP2106ACPZ-1.2-R7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。

GENERAL DESCRIPTION

The ADP2105/ADP2106/ADP2107 are low quiescent current, synchronous, step-down dc-to-dc converters in a compact 4 mm × 4 mm LFCSP package. At medium to high load currents, these devices use a current mode, constant frequency pulse-width modulation (PWM) control scheme for excellent stability and transient response. To ensure the longest battery life in portable applications, the ADP2105/ADP2106/ADP2107 use a pulse frequency modulation (PFM) control scheme under light load conditions that reduces switching frequency to save power.
