| Description & Applications |
PWM STEP-UP DC/DC CONVERTER WITH VOLTAGE REGULATOR AND DETECTOR ? Low Supply Current TYP. 55μA (RS5RM3624A : VIN=3.0V,at no load) ? Standby Mode Istandby=MAX. 1.0μA (RS5RM××××A) Istandby=MAX. 10.0μA (RS5RM××××B) ? Low Voltage Operation Possible Operating Voltage VIN=1.2V to 10V ? High Output Voltage Accuracy Fixed Output Voltage Accuracy±2.5% ? High Voltage Detection Accuracy ±2.5% ? Output Voltage can be set at User's request (refer to Selection Guide). ? Voltage close to battery's voltage can be output because these ICs are of a step-up / step-down type (Ex. a fixed voltage of 3V can be output by a 3V battery). ? Soft Start Function, built-in Protection Circuits for Lx Driver ? Phase Compensation Circuits built in ? Pin for External Driver is equipped, and a large current output can be obtained. ? Small Packages 8pin SOP ? Power source for cameras, camcorders, and hand-held audio equipment. ? Power source for small OA apparatus such as note book personal computers,and word processors. ? Power source for hand-held communication appliances such as pagers,cordless telephones, and cellular phones. |
| 描述与应用 |
PWM升压型DC / DC转换器 带稳压器和检测器 ?低电源电流 TYP。 55μA（RS5RM3624A：VIN= 3.0V，在无负载） ?待机模式Istandby= MAX。的1.0μA（RS5RM××××A） Istandby= MAX。 10.0μA（RS5RM××××B） ?低电压操作的工作电压VIN= 1.2V至10V ?高输出电压精度固定输出电压精度为±2.5％ ?高电压检测精度±2.5％ ?输出电压可设置在用户的要求（参见选型指南）。 ?电压接近电池的电压可以被输出，因为这些IC是一个升压/降压型 （实施例可以是一个固定的电压为3V3V电池的输出）。 ?软启动功能，内置的保护电路LX驱动器 ?内置相位补偿电路 ?引脚外部驱动装备，并可以得到较大的电流输出。 ?小型封装8pin的SOP ?电源相机，摄像机，手持音频设备。 ?电源的小型OA设备，如个人电脑，笔记簿，和字处理器。 ?电源手持通讯设备，如寻呼机，无绳电话和蜂窝电话。 |
