ADI ADP230x 1.2A超小型电流模式DC电源稳压方案

ADI 公司的ADP2300/ADP2301是集成了功率MOSFET的小型紧凑固定频率电流模式降压DC/DC电源稳压器, 输入电压VIN从3V到20V,输出电压从0.8V到0.85xVIN,效率高达91%,可选择开关频率700 kHz (ADP2300) 或1.4 MHz (ADP2301) ,超小型6引脚TSOT封装,主要用在系统内部电源转换,通信和网络设备,工业和仪表,保健和医疗设备以及消费类电子产品.本文介绍ADP2300/ADP2301主要特性,方框图,以及多种应用电路.

The ADP2300/ADP2301 are compact, constant-frequency, current-mode, step-down dc-to-dc regulators with integrated power MOSFET. The ADP2300/ADP2301 devices run from input voltages of 3.0 V to 20 V, making them suitable for a wide range of applications. A precise, low voltage internal reference makes these devices ideal for generating a regulated output voltage as low as 0.8 V, with ±2% accuracy, for up to 1.2 A load current.
